Im on ERFA now. Been on all the other dessicated brands in the US avail last year.
You say you feel sick on both brands. Define sick please. Like a fever from your infection or hypo symptoms?
Now on Armour, I feel ill like getting the virus, depressed and now feelings like on the edge of panic. Then, I calm down and can be fine. Usually it will last a few days but now finding it more and more common place in the last 2 weeks. On ERFA pulse was 106 at times-it has come down on the new Armour but still the top blood pressure number can be high and the bottom low. Pulse around 80-90. I'm on antibiotics for about the sixth time since dec. I had an abscessed tooth that they thought was sinus-it was pulled the first week of May. Then about a week ago, had another infection where tooth was pulled. I get this weird hypo,hyper feelings but sleep pretty good.
Sorry, I dont know. You need to separate thyroid symptoms from this tooth problem. Maybe you had too much ERFA, no mention of thyroid lab testing?
