My vitamin D level was extremely low #8. I then took vitamin daily 40,000 iu. It then became too high, my endocrinologist told me to stop it and also said my thyroid is normal ( I also started a new birth control camrese to prevent my severe migraines). Since then I am sweating excessivly, hair loss, fatigue, periods that will kind of stop and then continue now for almost 2 months. I am irritable, depressed, joints hurt, pain in back, pain thru my body. I sleep constantly, cannot function.
