Foggy thinking, diarrhea, fatigue, sensitivity to sun, loss of appetite ,weight loss, abdominal pain, hair loss, bloating, night sweats, chills, hot flashes, headaches, poor circulation, loss of breath. I do have GERD and had surgery for my chiari malformation and had my gallbladder removed (no gall stones-gallbladder was not functioning) vitamin D deficiency and low calcium. I am lactose intolerant. No IBS, no POTS, no blood problems. What's going on with me? This has been happening for 3 years now and no one can help me.
