My husband s shoulder hurt, wrists tingle, losing grip in right hand, legs hurt, knees hurt after sitting in a car for even just an hour. No known injury, just started one day and had continued for weeks. Tylenol does help, but does not eliminate the pain. It does not hurt for him to walk, but getting up from a sitting position and the first couple of steps are a challenge. He cannot put his arms up in the air and putting on a coat or shirt is a challenge. His appt. with his general practioner is a couple of weeks away - in the meantime, what could it possibly be?
