I have had a headache for over 2 and half weeks off and on and for 3 days persistantly. I have went to the E.R. and they did two CTs, one without contrast and one with of my head and sinuses, they were normal. The problem is I still have a headache with a lot of pressure in my forehead and in between my eyes. This gets worse when I lay down or bend over forward. I have a history of sinus problems and head aches but never lasting this long and usually motrin gets rid of it. I do have a little congestion but without signs of infection and do have occasional sneezing. My question is if the CT was negative for tumors and sinusitis, what else could be causing these symptoms? could it still be sinus related even though there is no sinusitis? Please help I will be seeing my family doctor in a couple of days but I do not know what else they can do, any Ideas please tell me. Thanks
