Hello and hope you are doing well.
What you had could be TIAs. TIA or transient ischemic attack, which as the name indicates there is a temporary lack of blood flow to a particular part of the brain. This usually recovers, but these people are more prone for strokes. For the TIA, if you are a hypertensive or diabetic, ensure to keep these under check. Eat healthy, a low salt and oily diet and exercise regularly. To improve blood flow to the ischemic areas plavix is indicated. The drug is used to prevent heart attacks, strokes, and to treat peripheral vascular disease and claudication. So, for TIAs the high risk factors are dealt with and to improve blood supply plavix is given.
Hope this helped and do keep us posted.
