My Name Is Vickie, And I Have High Blood Pressure.

My name is Vickie, and I have high blood pressure. Approx 7 years ago I had took a nap in a recliner. For some reason I startled awake to find I had no site in my left eye. The PA I saw said it might have been a TIA. Well, it happened again today, only I just had no peripheral vision in that eye. It's coming back, but what's going on?? Can you help me?
