"I'm only 40 years old and after a life time of urgency and frequency - Myrbetriq has changed everything! I can remember being in my early teens and having dreadful pain throughout the day - it's been like that until now. I've been on 50mg for about 3 weeks now no really side effect yet.  Except one that puzzles me - somehow it's relieved body and joint pain I've had for years. I have a couple of autoimmune diseases, so I always thought that pain was caused by that - and my doctors treated me for it too. I've tried finding information on if Myrbetriq somehow helps with pain, but I haven't found anything on it. Perhaps it's jjust a reaction I've had? It's just odd and I'm not one to just to conclusion but I can't help assume."
