heart beating faster, needles
and pin feeling in arms
and legs. gained a lot of weight. back
and leg problems. family dr sent me to a heart specialist, they took all kinds of tests and found nothing wrong. family dr took blood tests, cbc, can't remember what else. It took about 6 months to find out what was wrong. I was getting too much thyroid and had to get my dosage changed. This has happened 2 more times since then but now I recognize the symptoms and go to the end. dr first.
