for about three days I had a tingling pain in my right thigh. It felt like sharp tiny needles making a fan shape plunge into the thigh. At first I thought it was an edge of my key ring and keys pressing on the area. I discovered it was not the case. It seemed to be more prominent when I sat, and after three days has disappeared. Prior to the initial episode I had a small knot at the base of my left ear lobe. The tingling pain episode was felt just once today. I personally feel that a virus could have been the culprit. I had not fever.
