Hi, I am a concerned girlfriend. My boyfriend has been experiencing these problems for the last past month. He started getting pressure in the back of his head and down his neck, but the doctor's can't find anything wrong from his symptoms. He stares off and is also lightheaded. We have our concerns about tumors or cancer. We haven't gotten any head x-rays, etc. because he has no insurance. The doctor gave him an antibiotic but is not sure if it will work. I think the stress from having this so long has made it worse sometimes. If things do not get better in the next 4 days, the doctor told him to go to the E.R., which we will but will cost us a fortune.
