I have been having headache at the left base of my skull in the back of the head for some months now and is bothering me. Sometimes it radiates to the side and also earpain but there is no discharge. I also feel a needle pain near the middle of my head when I cough or sneeze. I have seen quite a few doctors who have prescribed me with muscle relaxant and antibiotics. I had a CT scan in September last year but all were clear. What could be the cause of my problem? It is worrying me so much and is affecting my daily work. I am 54 years old, weigh 110kg and 5ft 11 inch height.
