Recently, due to the radiating pain in the soles of the feet, I have undergone physical rehabilitation (electrotherapy and lumbar stretching), but there has not been significant improvement, including in the lower back.
Please help me identify the underlying factors, as this has deeply affected my quality of life.
I have already consulted a rheumatologist, and it was determined that the radiating pain in the soles of the feet is not caused by a rheumatic condition (the pain level in both feet alternates and is constantly changing).

Numbness and pain in the lower limbs may have two possible causes: 1.
A herniated disc causing sciatica, with symptoms radiating from the lower back, through the back of the thigh, down to the calf and foot.
2.
Poor circulation often leads to calf pain while walking.
For a herniated disc, it is crucial to rest in bed and maintain proper care of the back, avoid lifting heavy objects, sit with good posture, and not sit for prolonged periods.
If the issue is related to blood circulation, treatment with circulatory medications may be necessary.
If you have any questions, please visit the surgical outpatient clinic.

More Info

Understanding foot numbness and joint pain can be quite complex, especially when symptoms have persisted for an extended period, as in your case. Based on your description, it seems that you are experiencing a combination of foot numbness, joint pain, and a history of back and neck pain, which can significantly impact your quality of life.

Potential Causes
1. Nerve Compression or Entrapment: One of the most common causes of foot numbness and pain is nerve compression. Conditions such as tarsal tunnel syndrome, where the posterior tibial nerve is compressed as it passes through the tarsal tunnel, can lead to numbness and pain in the foot. Similarly, issues in the lumbar spine, such as herniated discs or spinal stenosis, can cause nerve root compression, leading to radiating pain and numbness down the leg.

2. Peripheral Neuropathy: This condition, often associated with diabetes, can cause numbness, tingling, and pain in the feet. It can also be caused by other factors such as vitamin deficiencies, alcohol abuse, or certain medications.

3. Musculoskeletal Issues: Given your history of back pain and the description of your symptoms, it’s possible that there are underlying musculoskeletal issues contributing to your foot pain. Conditions such as arthritis, tendinitis, or plantar fasciitis can cause localized pain and discomfort.

4. Circulatory Issues: Poor circulation can lead to numbness and pain in the extremities. Conditions such as peripheral artery disease (PAD) can restrict blood flow to the legs and feet, leading to pain and numbness.

5. Fibromyalgia or Chronic Pain Syndromes: If your pain is widespread and fluctuates, conditions like fibromyalgia could be a consideration. This syndrome is characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas.

Diagnostic Approach
To determine the underlying cause of your symptoms, a comprehensive evaluation is essential. This may include:
- Physical Examination: A thorough physical examination by a healthcare provider can help identify areas of tenderness, range of motion limitations, and neurological deficits.

- Imaging Studies: X-rays, MRI, or CT scans may be necessary to evaluate the spine and joints for any structural abnormalities.

- Nerve Conduction Studies: These tests can help assess the function of the nerves and identify any areas of compression or damage.

- Blood Tests: To rule out conditions such as diabetes, vitamin deficiencies, or autoimmune disorders.

Treatment Options
1. Physical Therapy: Since you have already undergone physical therapy, it may be beneficial to continue or modify your regimen. Focus on exercises that strengthen the core and lower back, improve flexibility, and enhance overall mobility.

2. Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation. In some cases, corticosteroid injections may be considered for localized pain relief.

3. Orthotics and Footwear: Custom orthotics can provide support and alleviate pressure on the feet, especially if you have structural issues like flat feet or high arches.

4. Lifestyle Modifications: Maintaining a healthy weight, engaging in regular low-impact exercise, and avoiding prolonged sitting or standing can help alleviate symptoms.

5. Alternative Therapies: Some patients find relief through acupuncture, chiropractic care, or massage therapy. These can be adjuncts to traditional treatment methods.

6. Surgical Options: If conservative treatments fail and there is a clear structural issue (like a herniated disc or severe nerve compression), surgical intervention may be necessary.

Conclusion
Given the complexity of your symptoms and their impact on your daily life, it is crucial to work closely with a healthcare provider who can guide you through the diagnostic process and develop a tailored treatment plan. It may also be beneficial to seek a second opinion or consult a specialist in pain management or neurology if your current treatment is not yielding significant improvements. Remember, addressing the underlying cause is key to finding relief from your symptoms.
