I have a burning pain periodically on to off my right thigh. I t seems like a nerve response. It comes unexpectedly. Started about 3 weeks ago when I was sitting. Then it would come only once a day, sitting, standing, walking--didn t matter. Some times it would skip a day. No redness or swelling on the leg. Several times recently it is sore to the touching that seems to trigger the sensation. Only lasts about 5-10 seconds and then goes away. Some times very painful, sometimes not so bad. Yesterday it happened 18 times. Today 12. I ve been keeping tack the last 5 days
