The day after my first Reclast infusion, I began experiencing intense bone and muscle pain. I've been taking the maximum dose of extra strength Tylenol for the past 10 days, which helps a little. At this point, I can barely function, and I'm angry most of the time. What is causing this horrible pain and will it ever stop? It enraged me to learn that Reclast is not more effective than the monthly pills that I had been taking without any side effects. I'M CERTAIN THAT NO PHARMACEUTICAL COMPANY WOULD PROMOTE A DRUG LIKE THIS FOR A CONDITION EXPERIENCED MOSTLY BY MEN. My doctor has no help to offer, and I definitely won't be seeing her again.
