"i had shoulder surgery back in july 2015. i was prescribed 50mg every 6 hours for pain. i took it just a couple days because i did not need much of it and the side effect dry mouth drove me insane. fast forward to november 2015. i&#039;m still experiencing severe pain in my shoulder 9/10. so i started using these sparingly whenever i feel like i want to be pain free. it works great and the dry mouth is worth the pain free time i get."
