I'm literally in agony! I'm swollen, the leg cramps are constant, my neck, back and head are killing me! I have fibromyalgia, chronic migraines, two slipped discs that I know of at the moment and all I can do is cry! I'm about to soak in the tub and my 14 year old has to prepare it for me and help me in and back out! I can't take much more😩
