Once every month or so I wake up feeling achy, whoozy, sore all over, with shortness of breath and welts all over my buttocks. I am 65 years old and had both hips replaced a few years ago. I told my doctor and he just gave me some antibiotics. The strange part is, it seems to disappear in a couple of days without treatment, but when it happens, I feel like I m going to fall down and die!
