What to do for burning sensation and excessive heat in body. Due to which there is a feverish feeling. I'm not having hyperthyroidism or any other disease. Still facing this issue since 6 months. Please help. Vitamin d25 level is 20 which is very low. As summer is here the heat seems to be increasing. Temperature remains 98.8 or sometimes 99.1 or 99.3 doctors said it's not fever. Could it be the side effects of medications i've taken before? Like anti-depressants and decongestants for bronchitis. I used to have tonsillitis very often and have ate a lot of antibiotics frequently but since october i'm not getting any infection. What to do? Is it something serious? I have anxiety and my depression is also increasing day by day because of this issue. I keep writing my question here. But I feel hopeless. That's why I keep asking. Please help me.
