Hi. I'm new here.
I have a 2 generation family history of underactive thyroid. The last 6-9 months I've had quite a few symptoms and it's not getting any better. The weightgain and unable to loose, weakness, dizziness, confusion, tiredness and shortness of breath are the reasons I went to my GP. Bloods were done and my TSH was 5 (apparently within normal range) and GP diagnosed Costochondritis for shortness of breath and take paracetamol . I just don't know what to do next? I really don't feel my usual self and I know there's something not quite right. I'm a personal trainer and shouldn't be this out of breath, tired and feeling weak. Your thoughts/opinions would be greatly appreciated x
