Returned yesterday from 3 days in the hospital. Rapid heartbeat and pain in the chest sent me to the ER. The heart enzyme tests showed that I'd had a mild heart attack but an echocardiogram showed my arteries were fine and there was no damage to the heart. They call me "the mystery lady". No mystery to me! It's been 2 weeks since stopping Levaquin after 5 pills of 500 mg. I've been suffering with constant headaches, severe neck, shoulder, arms and elbow pain and am convinced that the heart problems are all part of the results of taking Levaquin. I'm drinking Aloe Vera Juice, and taking calcium, magnesium, garlic, Omega 3 fish oil, and lots of water. No one seems to know what works!
