I developed tendinitis in my right arm out of nowhere- no change in exercise, no change in work (heavy computer use). Sometimes it was so bad I couldn't eat with my right arm because it hurt too much to bring my arm up to my mouth. As I puzzled over it (and wondered if it was just the aging process), my left arm started to develop the same problem. Then I realized it had started up around 6 months ago- same time I'd started taking Pravastat. I did a Google search and realized there was a likely connection.
I quit taking the darn things. That was early April; my arm gradually improved about 95%. I suspect the remaining damage is permanent, but I'll live with it. I get twinges only after very heavy activity.
When I finally got around to telling my doc, he suggested green tea capsules and another herbal supplement. I watch my fat intake very carefully and live an otherwise very healthy life- next week I'm attempting a race which is a 1000 meter swim, 9 miles on the bike and a 2.4 mile walk/run- and I'm 56.
But I'm through with statins. I'm fully convinced that if I were still taking them, this race would be out of the question.
