Suggest Remedy For Vertigo

Hi about 10 yrs ago I had a stroke the Dr put me on apo-diltiazem 180 mg ramipril 10 mg twice a day and 75 mg plavix a day. I have been having vertigo and light headedness since 3 months ago .my dr ordered a blood test and a ct scsn.the blood test was ok but the ct scan showed something going on there.He said I may have amimi stroke and to take a baby asprin with the plavix. Some of the things I read about taking the asprin & plavix are a bit scarey. what your feeling on this.
