Yes, n2l, what wysiwyg said. Some people can just have an underactive Thyroid, if you have Hashimoto's the reason it's underactive is because your body is making antibodies that are attacking your thyroid. You are also more susceptible to other autoimmune disorders like celiacs. Did they test your T3 and T4 levels, and antibodies too n2l?

I saw my Acupuncturist last night and he thinks he can help. He says he has seen lots of people with Hashimoto's and underactive thyroid and has improved it a lot for them. He is working on my immune system to try and fix it up. I have also in the last few months started getting hayfever and a rash under my wedding ring. He thinks it's all related and my immune system really needs some work. Acupuncture usually works really well for me with most things so fingers crossed it can help here too.
