Hi, I'm hoping someone can offer some insight, please. Excuse the long story but not sure if it is helpful context. Also, I'm a bit of a dunce when it comes to my thyroid so please excuse me if the answer to this is wildly obvious!
I have MS and about 6 years ago I had a treatment that recorded thyroid disease as a potential side effect. A couple of years after finishing the treatment I was 7 weeks pregnant with my first baby and due to my thyroid levels which were done via a routine blood test, I was told that I likely had Graves Disease. By the time I was seen by an endocrinologist I had switched from hyper to hypo so started on levothryoxine which I continued to take for 2 years. When I fell pregnant with my second baby, I went back to being hyper but at quite an extreme level. I started on carbimozale and have been taking that for the past 18 months. It has fluctuated a little and I've moved between 10mcg to 20 mcg a day a couple of times during that time. However, every month for the past 4 months, I've gone between the two, i.e. one month at 20, the next at 10, then back up to 20.
Fast forward to now (currently on 10mcg a day) and I had my bloods done yesterday by my GP as I've not been feeling well (fatigue, hunger, general fuzzy head) and they've come back with a TSH of 0.02, T4 of 10.2 and T3 of 3.8. I'm assuming that this means that my medication is too low but can anyone offer any insight of what may be triggering such a fluctuation? It all seems quite suddenly 'off'. I'm not under a consultant at the moment and we've just moved to a new area so I'm struggling to get any professional advice.
Thanks so much in advance
