Hi, I'm new to forums, or indeed social media of any type! I have. 10 year history of chronic shoulder pain and since Christmas have been in the worst exacerbation ever. I am now losing my will to keep going with it. I have been to a new pain clinic and had Botox which has partially worked, and have been prescribed Tapentadol which I can't get on with. It's making me lethargic, and feeling ill although it does provide better pain relief than Tramadol. I've had to abandon it though. Has anyone any experience of Tapentadol?
