I was just wondering what could be wrong, ever since I have been sick with a viral infection, I have had a numb/tingling feeling in my brain, and my right thumb is numb. A few days before I went to the Doctor, I had hit my head during training for a wrestling event, but the numbness and tingling did not begin until I started taking the medication for the illness. However I have stopped taking the medication 2 days ago, and still have the feeling. I never take any medication so I dont know if that could still be in my system or if I should see the doctor about the problems. What do you think?
