Tingling after hitting the head

Dear Amber: Possibly due to the hit on your head you are experiencing now a Neuralgia; this is could manifest as pain, tingling, numbness that follows the area or path supplied by the affected nerve, due to irritation or damage. You are having tingling sensation on the skin along the path or area of the affected nerve, then any touch or pressure is felt as tingling. The goal of the treatment is to reverse or control the cause of the nerve problem (if found), and provide pain relief. Treatment varies depending on the cause, location, and severity of the symptoms, and other factors. Generally, the condition may improve on its own or disappear with time.
