"i have been diagnosed with rheumatoid arthritis, raynaud&#039;s syndrome, and polymyalgia rheumatica (pmr).  since the 1950&#039;s i have suffered neck pain when doing a chore in one position for a long period of time.  i have exercised on a regular basis for many years and in 2009 i injured my rotator cuff on a piece of gym equipment.  after the physical therapy was finished i was experiencing sharp pain radiating from my shoulder to my neck.  i asked my doctor at the time, a rheumatoligist, if this was arthritis now coming from the shoulder.  he gave me a tube of voltaren gel to try and it has been wonderful.  i only rub two pea sized drops between my shoulder and neck in the morning and have no pain the rest of the day."
