Hi nervous, welcome and thanks for your question.  It's hard to say if this medication will help with the pain of arthritis.  I took Forteo and didn't get any benefit like that, but I have heard from others that it did give some pain relief.  I was also told, by my doctor, that Forteo can help with some types of pain.  There was a study done on pelvic fractures where Forteo helped tremendously with the pain from that.   Generally osteoporosis doesn't cause pain unless you've had a fracture.  Have you recently injured yourself or broken a bone?  If you are having new pain, I would talk to your Dr. about what's causing it.   Since we all react so differently to all medications it's really hard to say what your reaction will be.  I hope you do get some pain relief from it, but I can't say that will happen since there's no way of knowing that for sure.   Good luck and if you have any other questions just re-post.
