You seriously need to see a doctor about making a change in your medication. I have never taken Lupron, but if I had and started having those side effects, I run as fast as I could back to my doctor or to a different one.
I know LUPRON has alot of bad side effects, as for it me, it just made me plain crazy, I had terrible nightmares and was LIterally afraid to go to sleep which in turn caused more stress on me and then my hair started falling out badly because of it. As for your hands and feet I really don't know, have you looked up the sideeffects list and seen which ones you are experiences....you should probably do that and absolutely tell your doctor what is going on......good luck
