Hello, 28 year old male here...allways been healthy except for this... For at least 3 years now I have had these episodes of dizziness that seem to usually last about 2-5 days at a time. I get extremely dizzy and my vision becomes wavey immediately after I lay down on my back, or when I simply look up. Most recently, this has been in remission for about 5 months but Friday night I cut my eyes over to the left sharply for whatever reason and was immediately struck with severe dizziness...and it allways subsides within seconds of sitting back up. I had an emergency CT at the E.R. and was given Antivert/Meclizine which did seem to get rid of my dizziness 90%. I have had multiple contrasted MRI, MRA, CT, blood work, Echo/EKG for this before with all normal testing. Another major thing is for about the past 8-10 months I've had a moderate pressure headache behind my forehead and my nose constantly feels blocked...the nasal lining in my nose appears to be quite red, almost blood red. However I must inform you that my sinuses are allways crystal clear on the scans. I guess my question is, since the antivert works for the dizziness, does there seem to be a chronic infectious thing going on in my upper airways/vestibular system? could such symptoms be due to an upper neck problem? What opinion do you have based on my story? THANK YOU SINCERELY
