My mother was diagnosed at 52 with MS, and none of the treatments seem to be helping. She started getting sick around 45 and was constantly coming down with pneumonia. Recently, I have noticed joint pain and went to my general practitioner. When I mentioned cold hands with a tingling/numb sensation, sharp chest pains when I breath in, as well as multiple joint pain, she suggested it could be Lupus, arthritis, or Raynard's. After looking up all three, lupus fits my symptoms best since belching, mouth ulcers, and irregular periods arose about five years ago. My question is, could I have MS, or could my mom actually have been misdiagnosed, and have Lupus?
