Ive never felt this way

Yes everyday i have a headake but my heals are numb to the touch but painful when i streach out. the heat in CAlifornia doesnt help the pain. Ive tryed for SSI so i can take the time to get well and to find out the right meds to control the pain and stiffniss. Unable to recive it yet im going to apply again to get my MONEY i worked for. My back gets cramps to the point i feel like im being stabed in the back.My hands and arms ,shoulders as well feel numb and sometimes feel like i have a bone sper in my shoulder and my hands cramp up to the point i use wrist braceses. No matter what i hurt.
