I am 66 was screen 20 yrs ago for ms. Inconclusive diagnosis given told to go home and when I can not get out of bed come back. Well now I am having extreme itching mostly in hands and feet. Sometimes over different hit spots on body. Very painful muscle cramps to the point of years and can not walk.that happen even during exercising, walking. Hot flashing, way past menopause, sometimes feels like a fever. Has been happening for years, but at the point I am having trouble functioning. My question is can they still diagnosis me at this age???
