I've not been feeling well for a while know and went to drs the other week for tests. Ive been so forgetful it's been scary, I've been in tears over the least little thing and I'm struggling to loose weight. I was called in to the surgery this week for another test as my tsh was high and my t4 was in the normal range. Could I have a thyroid problem? Is there anything else I need the Dr to do?
