This all started a month ago,it started with presure on my eyes,and then progressed to the felling of not being able to breath at first I thought it was having panic atacks but now I have severe presure on the back of my head and back of my neak the doctor can't figure out whats wrong with me,he has done a ct scan and blood work to check all that stuff everything looks fine,my question is has any body else had this happen and if so what was it.
