I am a 27 year old male. A few months ago I experienced an illness no doctor has yet to find out what it is. I had severe head weakness and preasure. It also was in my upper jaw. I would also get this general ill feeling that would las only a few seconds. I went to my family doctor,an ENT, a Nuerologist, and an internist. I had EKG's done an Echocardiogram done, all was normal. I had a brain MRI done and a brain CT done. Also had a sinusus CT done. All of them showed I just had a sinus infection. After about a week of not getting aout of bed it finally started to go away and I felt OK for a few weeks. Now it has came back about two weeks ago. I went back to my family doctor and she gave me antibiotic for my sinusus infection and prednisone dosepak. I am taking flexeril from the last time this happened. I didn't take it then but I'm taking it now. I am finally starting to feel a little better. But I don't think it is any of the medicines I'm taking. I am also on Xanax and celexa. I just started Celexa a day or two ago. Im just worried about what can be wrong with my neck. There is no pain just severe weakness and when I stand up it tends to travel down my spine to between my shoulder blades. But my arms and legs feel fine. Any thoughts or ideas will be greatly appriciated. My neck weakness completely goes away only when I'm laying down
