Learn about the relationship between low back pain and fever, its possible causes, symptoms and treatment options.

Lumbalgia accompanied by fever can indicate various underlying medical conditions. Understanding the possible causes and symptoms is crucial for adequate diagnosis and treatment. Next, we will explore some possible conditions that can cause low back pain and fever, and we will offer a general description of its key characteristics.


Infections can be a frequent cause of low back pain and fever. A possible infection is that of the urinary tract (ITU), which occurs when bacteria enter the urinary system. Bacteria can move to the kidneys and cause pain and fever along with other symptoms such as frequent urination, burning sensation when urinating and murky urine. Another infection is that of the spine, also known as discitis or vertebral osteomyelitis. This infection affects the intervertebral discs or the bones of the spine and can cause localized pain, muscle stiffness and systemic symptoms such as fever.

Possible infections causing low back pain and fever:
Condition Typical symptoms
Urinary tract infection (ITU) Lumbalgia, frequent urination, burning sensation, murky urine
Spine infection (discitis or vertebral osteomyelitis) Pain located on the back, muscle stiffness, fever

Infections such as urinary tract and spine can cause low back pain and fever. Recognizing typical symptoms associated with these infections is essential for a precise diagnosis and rapid treatment.

Low Back Pain and Fever: Causes, Symptoms, and Treatment

The causes of low back pain and fever can vary, from minor conditions to more serious underlying medical problems. Among the most common causes are musculoskeletal disters or lesions, such as a muscular pull or a ligament break, which can cause localized pain and inflammation. Infections, such as urinary tract or spine, can also manifest with lumbar pain and fever. In addition, autoimmune conditions, such as rheumatoid arthritis or ankylosing spondylitis, can contribute to these symptoms.

Key Symptoms of Low Back Pain and Fever:

  • Pain located in the lumbar region
  • Increased body temperature (fever)
  • Reduction of movement amplitude and flexibility
  • Swelling or inflammation in the affected area
  • General discomfort or feeling of discomfort

Treatment Options:

  1. Rest and avoidance of activities that exacerbate pain
  2. Application of cold or hot compresses in the affected area to relieve inflammation
  3. Free sales analgesics, such as no n-steroidal ant i-inflammatories (NSAIDs)
  4. Prescription medications for more intense pain or underlying infections
  5. Physiotherapy exercises to improve the strength and flexibility of the lumbar zone
  6. In severe cases, surgical intervention may be necessary to treat the underlying cause of pain.

It is important to seek medical attention if lumbar pain and fever persist or get worse, since they can be indicative of a more serious condition that requires immediate treatment.

Understanding the Relationship Between Low Back Pain and Fever

Lumbalgia, also known as Lumbago, is a common ailment among people of all ages. It can vary in intensity and duration, and may be caused by various factors, such as muscle disters, discos or degenerative conditions. On the other hand, fever is usually a sign of an underlying infection or inflammation in the body. It is usually characterized by an increase in body temperature above the normal range of 37 ° C (98. 6 ° F), indicating that the immune system is actively fighting an infection.

Important information:

  1. The presence of both low back pain and fever can indicate a possible systemic infection or inflammation in the body.
  2. It is crucial to determine the underlying cause of the symptoms to provide adequate treatment.
  3. It is strongly recommended to go to the doctor when experiencing low back pain and fever, especially if additional symptoms such as chills, night sweats or weight loss are presented.
Underlying causes Additional symptoms
Infection in urinary tract or kidneys Urgency, frequency or pain when urinating
Infection or abscess in the spine Located sensitivity, pain worsening with movement
Viral or bacterial respiratory infection Cough, throat pain, congestion
Systemic inflammatory disorders Joint pain, skin rashes

Common Causes of Low Back Pain and Fever

1. Infections: Infections can often cause lumbar pain and fever. A common infection that can cause these symptoms is an urinary tract infection (ITU). An IU occurs when bacteria penetrate the urinary system and can cause pain in the lower back, along with fever. In addition, other types of infections, such as renal or those of the spine, can also pursue with low back and fever.

  • Urinary tract infection (ITU): Bacterial infection in the urinary system can cause low back pain and fever.
  • Renal infection: An infection that affects the kidneys can cause low back pain and fever.
  • Spinal infection: Infections that affect the spine can cause both low back pain and fever.

2. 2. Inflammatory diseases: Certain inflammatory conditions can contribute to low back pain and fever. One of them is ankylosing spondylitis, a form of arthritis that mainly affects the spine. Inflammation of the spine can cause lower back pain and fever. Other inflammatory diseases, such as rheumatoid arthritis or systemic lupus erythematosus, can also present these symptoms.

  1. Ankylosing spondylitis: Inflammatory arthritis that mainly affects the spine and causes low back pain and fever.
  2. Rheumatoid arthritis: Inflammatory joint disease that can cause low back pain and fever.
  3. Systemic lupus erythematosus: An autoimmune disorder that can cause inflammation and pain in various parts of the body, including the lower back, along with fever.

It is essential to seek immediate medical attention if you experience lower back pain combined with fever, as it may be a sign of a potentially serious condition that requires treatment.

Symptoms and Signs to Watch Out for

1. Low back pain:

  • Discomfort or severe pain in the lumbar region.
  • Persistent pain that worsens with movement, especially when bending or lifting weights
  • Pain that radiates to the leg(s)
  • Numbness or tingling sensation in the lower extremities
  • Difficulty getting up or sitting down

Low back pain can be caused by a variety of factors, such as muscle strain, herniated disc, spinal stenosis, or even an underlying medical condition. It is essential to seek medical attention if the pain is severe, persistent, or accompanied by other symptoms such as fever, bowel or bladder dysfunction, or unexplained weight loss. Early diagnosis and appropriate treatment are crucial to prevent possible complications.

2. Fever:

  1. Elevated body temperature above the normal range.
  2. Fluctuations in body temperature, usually accompanied by chills or sweats
  3. Headache and body aches
  4. General weakness and fatigue
  5. Loss of appetite

Fever is a common symptom that usually indicates an underlying infection or inflammation in the body. Although mild fevers can usually be treated at home, it is important to consult a healthcare professional if the fever persists for more than three days, is accompanied by severe pain or other concerning symptoms, or affects infants or people with a compromised immune system. Prompt medical attention can help identify the underlying cause and guide appropriate treatment.

Note: It is important to remember that the previous symptoms and signs are orientative. It is always recommended to consult a health professional to obtain an accurate diagnosis and personalized advice.

Diagnosis and Medical Evaluation for Low Back Pain and Fever

When a patient has low back pain and fever, the thorough medical evaluation begins with obtaining a detailed medical history. The health professional will ask about the duration and intensity of the symptoms, any previous episode of similar pain and any associated factor, such as recent infections. In addition, the patient’s medical history will be reviewed to identify any pr e-existing condition that can contribute to symptoms.

  • Next, a complete physical examination is performed, focused on the back and on the signs or symptoms that accompany it. The healthcare professional will evaluate the amplitude of movement, muscle strength and the neurological function of the patient. This exam is aimed at detecting any anomaly or indicator of a specific condition that can be responsible for lumbar pain and fever.

IMPORTANT NOTE: It is essential to take into account the possibility that there are serious underlying conditions that cause low back pain and fever, such as spine infections, vertebral osteomyelitis or systemic inflammatory diseases. A rapid and precise diagnosis is essential to guarantee adequate treatment and minimize possible complications.

  1. Image diagnosis plays an important role in the evaluation of low back pain and fever. Radiographs can be the initial image modality to identify any structural anomaly or fracture, but it is possible that they do not properly visualize soft tissues or certain spine conditions. Therefore, additional image studies such as computerized tomography (TC) or magnetic resonance (RM) to provide more detailed information on suspected pathology may be necessary.

Image diagnostic modalities Advantages Inconveniences
X-rays – Fast and easily available – Limited visualization of soft tissues
Computed tomography – Excellent visualization of bone structures and possible infections – Radiation exposure
IRM – Detailed evaluation of soft tissue structures and spinal cord – It requires a lot of time and is relatively expensive

Treatment Options for Low Back Pain and Fever

1. MEDICINES: Free or recipe venues, such as no n-steroidal ant i-inflammatories (NSAIDs) or paracetamol, can help relieve pain and reduce fever. These medications should be used following the indications of a healthcare professional and should not be taken for prolonged periods without medical supervision.

  • NSAID: no n-steroidal ant i-inflammatories, such as ibuprofen or naproxen, can help reduce pain, inflammation and fever associated with low back pain. It is important to follow the recommended dosage and take these medicines with food to minimize the risk of stomach irritation.
  • Paracetamol: Paracetamol can be effective in relieving pain and reducing fever. However, it is important to avoid exceeding the recommended dose to prevent possible liver damage.
  1. Rest and physiotherapy: the right rest is essential to allow the body to heal and recover from low back pain and fever. However, prolonged bed rest must be avoided, as it can cause muscle stiffness and more complications. Physiotherapy exercises prescribed by a healthcare professional can help strengthen the back muscles, improve flexibility and favor healing.
  2. Cold and heat therapy: Apply heat or cold in the affected area can temporarily relieve pain and reduce inflammation. A thermal pad or hot compress can help relax the muscles and increase blood flow, while an ice bag can numb the area and reduce inflammation. It is important to use these therapies for a short time and avoid applying them directly on the skin to avoid burns or freezing.

Note: If lumbar pain and fever persist or worsen despite conservative measures, deeper research and specialized medical intervention may be necessary. Consulting a healthcare professional is crucial to guarantee a precise diagnosis and proper treatment.

Prevention and Home Remedies for Low Back Pain and Fever

Precautionary measures:

  • Maintaining a good posture: a bad posture can tighten the back muscles and cause pain. It is important to maintain a correct posture when sitting, standing and lifting heavy objects.
  • Exercise regularly: regular physical activity can strengthen back muscles and improve flexibility, reducing the risk of low back pain. Low impact exercises, such as walking, swimming and doing yoga, are especially beneficial.
  • Avoid staying for a long time sitting or standing: being sitting or standing for a long time can overload the lumbar area. It is essential to make periodic breaks and stretching to relieve muscle tension.
  • Raise with the legs: when lifting heavy objects, it is essential to use the legs instead of the back to avoid forcing the muscles.
  1. Apply heat or cold therapy: Applying a heating pad or ice pack to the affected area can help reduce inflammation and temporarily relieve pain. Heat therapy is especially effective for muscle spasms, while cold therapy is beneficial for reducing swelling.
  2. Practice relaxation techniques: Stress can exacerbate lower back pain and fever. Relaxation techniques, such as deep breathing exercises, meditation, and progressive muscle relaxation, can help relieve stress and promote muscle relaxation.
  3. Use over-the-counter pain relievers: Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or acetaminophen, can help reduce pain and inflammation. However, it is important to consult with a healthcare professional before taking any medication, especially if there are underlying medical conditions.
