When I was 14 I was diagnosed with hashimoto's and for years I was on 0,5 mg thyrax a day and was fine, until about 1,5 years ago. I got a weird rash, started having trouble breathing and swallowing and my voice got very 'stiff' (which is not a good thing for a student of classical singing). By accident I was stuck without thyrax for a weekend and the symptoms disappeared, also I didn't get any symptoms of hypothyroidism.
I felt perfectly fine for about a year, then the trouble swallowing and breathing and the feeling of a lump in my throat returned. The doctor put me on euthyrox and told me to start building it up with a quarter pill every 10 days.
This seemed to relieve the symptoms for the first 4 days, but then they started getting worse again, so eventually I had to stop taking the meds. Again the symptoms disappeared for a few days and started building up again.
I'm now 6 months further and the only thing that sort of works against the symptoms is switching from using a quarter pill for a few days and then nothing for another few days. According to my doctors this isn't possible, but it's the only thing that works for me. So I was wondering, could it be that I'm allergic to the levothyroxine and the allergy symptoms are the same as the hypo symptoms? Or has anyone an idea what it could be?
I'm starting to get really desperate, since the doctor(s) are not of any help, but the symptoms aren't getting any better either.
