Hi! I have underactive thyroid (200mg lexo) and also hashimotos. My last blood test showed my ferritin was high so going to an endo in sept, but I have noticed my breathing is always very shallow and then I have to take a very deep breath. I am sighing a lot To and huffing and puffing. My body aches if I have a busy day at work physically and can end up hobbling after. Any thoughts?
