Does anyone know if this could be consider chronic pain. I was diagnosed 8 years ago. Havent been back to the doctors since then. normally its just an ache when i use the shoulder alot, with a flair up a few times a year. during the flair ups my entire arm is useless. doctors perscribed vicadin 8 years ago to help me sleep thru the pain, with a double dose it would help me sleep for about 2 hours. A friend on mine has a perscription so I have been just visiting him when my shoulder was achy. Any advice would be appreciated.
