At 67 years old with Osteopenia and Osteoarthritis I  was having issues sleeping due to pain even though I take 3 Ibuprofen at bed time along with Voltaren cream on arms, shoulders neck and upper back.  I ordered this after getting steroid shots in both shoulders, although the pain in my joints was relieved the muscles down both arms across shoulders, neck, and upper back was horrible and no position made the pain bearable.  This has helped greatly as long as I don't overdo during the day, a real life saver.
