I have had some vertigo for about two months now. when I saw my neurologist he ordered and mri of the brain but said I may need to see an ear nose and throat doctor. I have not heard anything about my mri so I took for granted it was ok. I started to take some Sudafed and this seem to help but I get a headache sometimes also. is it harmful to take the Sudafed just to see if this might clear it up. I also tried some over the counter meclizine which helped a little but not as much as the Sudafed. any thoughts would really help.
