Hi Guys. I had my little girl back in 2012 and had post partum thyroiditus. I only had the hyperthyroid phase though. I was never told what i had but i dont remeber getting the hypo phase of it. Anyway i felt fine after a little while and have been fine ever since. 3 weeks ago i started a new job, longer hours and more stress as im in charge of the kitchen. about 10 days ago i got a sore throat and felt just a bit blergh. I have a busy life, 3 kids, football at weekends and running a house. the usual. I thought i just had a virus but then a few days in started to get mild dizzy spells, if i was standing up i would feel like the room was spinning for a few seconds and i get a bit breathless plus i have a resting heart rate of about 84bpm. I dont have any other symptoms they are it. My throat has got better and my cough has gone but i still feel sort of light headed. I feel fine when lying down though. I went to the doctor and he felt my neck and has asked for thyroid function tests and anemia tests. Does this all sound like my thyroid id playing up again? Im not sure if because im worrying it is exagerating my lightheaded feeling. Im so terrified of it being my thyroid again. My life was just going good, better job etc you know. sorry for rambling. No one really understands what im on about at home because i look fine on the outside.
