A herniated disc in the lumbar spine can cause pain in both heels. But heel pain is not necessarily caused by the patient’s lumbar disc herniation. Most patients with lumbar disc herniation will suffer from pain in various parts of the body due to undirected protrusion of the lumbar disc compressing the nerves, and the reason for the heel pain is that when the patient’s fifth lumbar disc is herniated, the nucleus pulposus presses on the nerve roots associated with the feet. This symptom is exacerbated when the patient engages in activities such as coughing, sneezing, defecating, and other activities that cause an increase in abdominal pressure. Heel pain in patients with lumbar disc herniation may also be caused by Achilles tendon injuries resulting from short periods of high pressure or prolonged strain on the patient’s heel. The biggest difference between Achilles tendonitis and heel pain caused by lumbar disc herniation is the presence of obvious pressure points. Patients can relieve the symptoms through conservative treatments such as bed rest. If the pain cannot be relieved, they should go to the hospital for timely medication or surgical treatment.
