There is not much correlation between heel pain and sciatic nerve. A herniated lumbar disc compressing the sciatic nerve may lead to numbness in the heel, but the chance of pain is low, and heel pain is mostly considered to be caused by Achilles tendonitis and osteophytes, which can be treated by medication and surgery, etc. The sciatic nerve is the largest and thickest nerve in the body. The sciatic nerve is the longest and thickest nerve in the human body, and a bulging lumbar disc may compress the sciatic nerve root, resulting in radiating pain in the lower limbs, but it usually occurs on the back of the foot, and numbness is the main cause of heel pain. Therefore, patients with heel pain should not think too much about the association between pain in this area and the sciatic nerve, which may be caused by Achilles tendonitis or osteophytes. Patients are advised to go to the hospital for a detailed examination, and after confirmation of the diagnosis, oral non-steroidal anti-inflammatory drugs such as diclofenac sodium can be used for pain relief, and surgery can also be considered to repair the bone spurs or osteophytes.
