Hi, your bad reaction may have been a herx, all your symptoms come back ten fold. Sometimes can mean your on the right track, just got to ride it out. But I am not sure this is the case. Have you ever had thyroid tests? Thyrotropin deficiency of the pituitary has some similar symptoms. Have a research into thyroid/ pituitary ailments, just a suggestion. I wish you all the best and hope you find your answers.
