Hello sir, i is suffering from unbearable burning in the thigh of his right leg since few days due to which we have shown many doctors, took medicine continuously for 20 days but no relief sir what can we do to get relief and recover?

Not feasible to be precise without a direct exam, but you likely do have neuropathic pain. Most commonly this would involve lateral femoral cutaneous nerve (meralgia paresthetica), but could also be referred from hip or lumbar spine. Find a neurologist and get further assessed, but we could also do a virtual consult here at HT (www.connect@healthtap.com).

I would suggest to avoid wearing tight pants and skip belt that may cause additional pressure on the nerves, I would also suggest to lose some weight if you are on the heavy side. You could try liniment with capsaicin and see if that helps. Leg exercises to reduce pressure on the nerves if done regularly may also help.
