I too am on Aromasin and cannot bend my fingers. I am only 52 and feel like I'm 90 years old when I get up after sitting for a period of time. After my chemo/radiation I felt like I was getting my life back. I walked daily, went back to my yoga and kayaking. I felt great. Then they put me on Arimidex. One morning I woke up and couldn't move. My hands and feet were swollen and cramped. My oncologist took me off all medication to see if I felt better. Within a couple of weeks, I was back to normal. He then suggested Aromasin. I've been on it for two months and am having pain and swelling in my hands. I am an art teacher and a potter. At first I thought maybe it wasn't the medication, maybe I was developing arthritis in my hands. But after reading your e-mail, I realize it's the medication again. Why doesn't the literature on these meds. mention this side effect? I am making an appointment with my oncologist and bringing these e-mails. I want him to see that this is not a "rare" side effect. There has to be a remedy for the pain and discomfort without going off the meds. Please let me know if you hear of one, and I will do the same. Sharon
