Hi! I'm a 46 year old female. You could say I'm a pretty big health fanatic. I've always been interested in health and fitness, nutrition and exercise. I have stepped up my nutrition a notch, but I have slowed down some on the exercising, although I get alot of walking in, at my job. I was diagnosed with a mitral valve prolapse back in 1990 and I also had anxiety problems which produced heart palpitations among other symptoms. My doctor prescribed atenolol, (a beta blocker and high blood pressure pill) for me. I've been on this ever since.I also have hypoglycemia (low blood sugar) , which I keep in check with proper nutrition. About 2 months ago I was at work and my ears started feeling like they were getting clogged I seen black dots in front of me and felt like I was going to pass out. I sat down quickly and it slowly passed. Ever since that time I've had repeated episodes along with feeling off balance, alot of the time and nauseated. Sometimes my eyesight gets blurry. I've been in the hospital emergency room twice now in the past three weeks. I've had blood work done, an EKG, urine test. Everything seemed to check out ok, but my blood pressure was high. I've been skimming over the internet in search of something..... and all I come up with is confusion. I stumbled over this forum by accident and thought I'd give it a try and see if there is someone out there who might be able to help me. I'd like to hear from anyone who might have the same problem or anyone who might be able to give me some input or advice. Thank you!
