I am a 47 year old female. I have Osteoarthritis and Fibromyalgia. I have had 2 hip replacements. My problem now is my feet. I have painful knots on the bottom of my feet and the side of my feet. My heels hurt so bad and generally it just hurts to touch my feet. They stay hot all the time. I don't know what's going on and thought maybe someone may be able to help me. Thank you.
