Hi B'S Girl! I have had fibromyalgia for at least 10 years and osteoarth. My Rheumotologist after trying me on quite a few medication ,because of severe side effects has put me on a pain med. I know about liver damage from the tylenol in them but I was just at my Dr's and they did blood work to check my liver functions and did a urine test. I think that what is sad is that there are a lot of abusers of pain meds. out there! It makes it difficult sometime for honest people to get pain meds. I do not abuse them and my Dr. was so surprised at how long they lasted me. Sometime a pain med. is what helps above all the other things we try. When the pain gets so bad then you take it.We learn to grade the pain so as not to become abusive.As for the tylenol,that stuff is dangerous in any circumstance and I wish they could replace it with something else.It never helped me to take tylenol for migraines. I have also heard good things about the Mayo Clinic in Fl. In Jax. I can see a new type of Doctor emerging in the near future,Those who deal only with post cancer patients. We are not nuts or hypochondriacs .we are sick and in pain!!!! I like to tell people when they say well....where do you hurt? I hurt from head to toe and inside out! I am no longer able to do my job and that makes me sad. I wish you the best and do hope that you get some very good help. We are smart happy and good people from all walks of life and cancer treatment is part of that life. I truly do wish that people would get educated on the after affects of cancer treatment!                                  God bless you,                                              Gail
