Dear Doctor, I am resident of Delhi NCR. During the changes in seasons
Hi Mr Chan Chat Doctor. Feeling of pain, heaviness/fatigue in legs is caused by stenosis or narrowing of the central canal in the spine where the nerves are pinched. L5, S1 and L4 are the common ones to get compressed. The cause of this is degeneration of the spine which means age related arthritic changes in the spine. The intervertebral disc bulges, bone spurs from the vertebrae (osteophytes) and a thickened ligament between vertebral bones contribute to this stenosis. Initial line of treatment for this is pain relieving medications, brace and physiotherapy. Epidural injections are done in spine around the affected nerves and reliably offer pain relief. All these treatment options relieve pain but unfortunately none of these can sure the basic pathology causing this pain for which surgery is necessary. Hope this is helpful. I would be happy to answer any questions you may have.
