My hv recently noticed my neck looked swollen so I was referred to GP who organised bloods. Turns out I've got an under active thyroid probably due to having a baby 6 months ago. My tsh was 99 ( should be no higher than 4) so GP suggested thyroxine while I wait to see endo consultant. I've not started thyroxine yet as I'm bf but as this has affected my supply and I now feel pretty crap ( knackered aching sore throat etc) I've started weaning DD and want to start treatment just after some advice/ similar experience really
