Hi, Sometimes I have so much stiffness and pain in various areas of my body that I have to have someone put on my pants or my shirt, etc. For example, I had an attack a week ago and two days later I woke up with such severe pain in my right shoulder and upper back underneath my shoulder blade that I was unable to lift my arm above shoulder height and I needed help putting on my shirt. I couldn't use that arm to shift out of park and I drove primarily with only my left hand. The pain was so severe at night that Percocet only took the edge off it. THe stiffness/weakness and pain lasted for about 5 days, really bad for three days. Now, it is almost entirely gone and my mobility is back. I have had this before and I get similar things with other joint areas with my sacroiliac being the worst. This in my humble opinion does not fit with either chronic fatigue or Fibromyalgia. I would appreciate any comments and personal examples. Thanks.
