I have Metastatic Melanoma and was treated with Keytruda for a year. It killed my Endocrine system, including my Pituitary gland, Thyroid, Adrenals, and everything else. I take NP Thyroid for HT, Cortisone 2X daily for Adrenal insufficiency. I am suffering from Chronic fatigue that’s had me in bed for 12 weeks. I am too tired to get up. I feel like I’m feverish and have spells of convulsive chills, followed by drenching sweats, usually at night. When I check it, my body temp has been at . I stopped taking Synthroid because it was making me feel bad and went to NP Thyroid. I almost immediately felt better….for about 3 months, then the fatigue started. My labs look normal but I know that they shouldn’t necessarily look normal when on NDT when the lab is testing for normal levels when on Synthroid. I would appreciate any thoughts from anyone.
