You need some good stuff soon. Sorry you are feeling so bad, I hope a change of medication helps. I have been on Femara and apart from knocking my bone density about a bit (known side effect and luckily mine was very good so I have some wiggle room) I have had no side effects that I am aware of. No aches or arthritis like symptoms, no flushes. I switched to Arimidex to see if it would help a hair problem that turned out to be (I hope!) temporary but to be honest I didn't have any side effects on that either. Didn't improve the hair so back on Femara. Good luck with everything.
