Hi Doc, my name is Anonymous, I m 30 years of age and my weight is 100 kg. I m HIV positive n I ve been on treatment for 9 years now. I have a problem, I sweat too much on the face ever since I was 15 years old, whether it s cold or hot or any season, I sweat and get shaky when I m hungry, I forget a lot and I m also losing my hair and having heart palpitations and hot flashes, my stomach is always lose and I also have rash on my body (small sores). I have been to the doctor to check test for Hyperthyroidism but the results came back negative. What could be the problem?
