I ve been having discomfort in my right shoulder, originally thought slept wrong, it s now 3 weeks. I have moved my mousepad when I realized not ergonomically correct, unsure how long to wait to see correction. I am experiencing trouble lifting elbow upward without pain in shoulder area and pain when putting on and removing bra from back, as well as trying to put arm in jacket sleeve. In addition, trouble sleeping without discomfort. Haven t fallen.
