l live in a tropical place. l will be sitting in a room without AC and suddenly l start feeling very cold. Then l will start to sneeze uncontrollably. My eyes start watering and then my throat gets soar. In the hot weather l take a blanket and then after a few minutes my body temperature regulates itself. l have had my thyroid checked a few times and it is normal. Please advice.

Clearly, there is something amiss in the metabolic system. l am going to stick with the thyroid, but there r myriad other possibilities. Many thyroid tests miss small discrepancies that can contribute to hypothyroid issues. About the only thing u can do is read up on alternative treatments & stay as healthy as u can. l would also look into immune system boosters as an underlying chronic disease could be contributing to ur metabolic issues. Ask this again in the health/alternative medicine section where there r several altmed gurus that might be able to give u far more help that l can.
