I'm not sure I'd say that Arimidex went on the market too soon. It was proving to be something that could help many people survive longer. The side effects are simply that; side effects. Those that were bothered more than they could tolerate can be taken off and put on something else but those of us that can put up with the aches, pains, and odd occurances, are better off, I think, with the medication.
The problem, as I see it, is that perhaps people that were being bothered with the "trigger finger" and such had no idea that it could be related to the Arimidex until enough people were getting together and comparing symptoms. I credit the Internet with our ability to do that in ways never dreamed of before. No way could enough doctors know that this was something related to the drug until enough people said something. Not only about their own symptoms but of others they had talked to. There are still quite a few doctors that don't know anything about this. I, for one, am trying to spread the word.
My doctor took my word for it and then read the literature I received from Astra Zeneca. He then sent me to Occupational Therapy for the problem and they've helped very much. I am hoping that I only have to finish the therapy I'm doing now for the right hand and the left, where the biggest problem was, has been doing quite well. In one of my jobs, (I have several), I handle lots of things like expensive crystal vases, plates and such to engrave them. I have to be able to trust my hands to keep working. And, If the Arimidex keeps doing it's job, I'll be around to engrave many more.
