We diagnosed my husband with hypo with a private blood test and clinical symptoms - his T4 is very low. For a couple of years he has been having "funny turns" - almost faints, and says he feels his chest "welling up". We had to ask for a chair in Lidl's yesterday. Do we think that this is hypo related or something else completely? He is 65 and last time he had his blood pressure done a few weeks ago it was OK, and he has recently had a "well man" check up which was also OK. Any ideas???
