Hi Angela,
It doesn't really matter at this point whether or not it is the Prozac that is causing your pain. Call your doctor now and tell all - whether you get the answering machine, the secretary, or doctor, tell the entire problem - all your pain, etc and ask for immediate advice...........you are the person with the pain...take control! Don't suffer any more.
If it's the meds, there are many more to choose from. You may have some other problem that should be checked right away. Do it now!! Don't be afraid.
Take care,....good luck with it.
