Talk to General Surgeon on Head Injury

I had an road accident 3 months ago in which I got a blow on left side of forehead and also my glasses broke due to which skin was teared on my left side of forehead, there were many small pieces of glass doctors washed it off and stiched it, total 8 stitches. In CT scan that happened on the accident day everything was normal according to doctor its been 3 months but still left side of my forehead and head feel like numb (as if some layer has come over at that part), also I feel like ant is moving upward to downward and downward to upward in left side of head many times in a day, although I got stitches only on the forehead not at head. And sometimes sharp pricking in left side of head.
