This started for me last spring. Then it dissipated. Now it is back. I fall asleep after taking my Advil Tylenol combination plus two antiacids at 10:30 and wake up at 2:30 to use the bathroom than about 3:45 to 4:00 wake up with my upper body and arms aching so much and I start to cry from the pain. At this point I have been taking another Advil to stop the pain and fall back to sleep until 6. I have no pain when I fall asleep at 11.
