Thanks for you reply!!!
I did consult my doctor. BP and blood work looks good. I'm generally very healthy and this happened right after I started applying minox. Anyways, my doc gave me anti vertigo meds for a week, but so far that's not of much help! I've read in other forums that it could take up to a month for some of the side effects to go away.
