Hi, Im 59 yeas old.My health is good. Not overweight, generally fit an take good care of myself and what I eat. I have been on BP medication for many years (i'm told its hereditary - Mom and Dad both had it). My tinnitus is something I have become accustomed to. Three days ago, I didn't feel well but couldn't put my finger on any one thing. My BP was normal although my heart rate was elevated. I lay down, feeling dizzy. Over a period of 12 hours I had very loud bursts of sound in both ears - so severe that my head twitched involuntarily. I say my MD who said that when it happens again, I must go straight to the ER. I'm really scared. My father died aged 62 from MCI. I have had an ECG which showed only slight abnormalities. Can anyone explain this to me? Thank you.
