Hi Mohan. A damaged nerve like this can be hypersensitive and irritable. It can continue to fire even when the stimulus that triggered the firing is gone. This is called a "hyperesthetic nerve" or neuritis. There are some treatment options we can go over.
What information do you need, sir?
There are several things you can do to help with this type of nerve condition. First, you must keep your blood sugar levels under good control (ideally below 130 fasting) so there is less stress on the affected nerve or nerve. Second, if there is any swelling in your leg, you should wear compress stockings and elevate your leg whenever you can (above the level of the heart when possible.) In addition, you will likely need to use a combination of medications to settle the nerves down and keep them from firing spontaneously. For example, you can use capsaicin cream topically to calm the affected nerves . This agent can be very helpful in treating neuropathic pain if used properly. In addition, you should take a nerve stabilizing medication such as gabapentin or pregabalin that raises the firing threshold of the nerves making it harder for them to fire. This medication is widely used for neuropathic pain and may be highly effective when used for several weeks to months. If these agents prove unsuccesful at controlling your pain, you should see a pain management specialist. This is a doctor with special training in managing painful conditions (often an anethesiologist). He or she can inject the affected nerves, if necessary, with a medication that turns them off completely.
