I have some arthritis in both arms its knocks the wind out me sometimes. Maybe rode a motorcycle to long i do not know and been out in elements or probably just getting old. Its really messed up my Guitar playing Can not play it for to long anymore. My question I have an abscess above a tooth. I am taking Asda's Long lasting pain relief Ibuprofen which last 12 hours and is very good. How come these pills can knock out the excreting pain of a abscess. But dose nothing for the pain in my arms. How dose this work i am again intruiged. Any doctors or nurses on here Tell me please.
