Hi there, I sustained a very deep laceration to my right leg, just above the knee, approx 2 years ago. Months later, I started getting a tingling sensation in that same leg, above where the laceration was when I sit, squat or lay down and is also accompanied by hypersensitivity to soft touch which has now spread to the entire outer thigh. Sometimes I also get an EXTREMELY painful tearing feeling. My doc has ordered a CT Arthrogram to see if there is nerve damage. Is this the correct scan???
