I’m sorry you’re having such a bad time! Your TSH was very high at >100 and your T4 level of 3.1 is well under any range that I’ve seen. This often means that you’ve been hypothyroid for quite some time before diagnosis and consequently means that it can also take a considerable time to get well again.
A ‘normal’ TSH after 6 weeks does NOT mean that you are well again by any means! It just means that you are back within the blood test range, this varies around the country but it’s usually somewhere in the region of 0.5 to 5.0 (N.B. ask for your ranges for all tests each time). Also most of us need to get our TSH to around 1.0 or even below in order to feel well again.
Becoming hypothyroid is usually a gradual process and it’s a gradual process getting well again too. Being hypothyroid affects every part of your body and it takes time to repair itself again. It must be really difficult with 2 small children but try to get some ‘me’ time each day and relax if you can. Meditation techniques can help a lot as can pacing yourself too. You’re probably permanently tired so just do what is essential; it doesn’t matter if the house needs dusting etc, just concentrate on what absolutely *has* to be done.
Accept ALL offers of help!! Also ask for help too, people don’t always realise that you’re struggling if you don’t say so.
My legs used to get really sore too. Sit down with the children, put your feet up and read them a story or watch some telly with them for a while if your legs are sore. Don’t stand if you can sit, even just chatting to someone always try to sit down if you can. Get a tall stool to sit on when washing up, peeling the potatoes, ironing etc; it really can help.
Are you taking the Erfa and thyroxine all together in one go or spacing them out over the day? Erfa has T3 in it and this is much shorter acting than thyroxine – many of us who take it find it’s better to take it twice a day or even more often if particularly sensitive to it. I take mine when I wake, around 6 to 7am and then again somewhere between 1.30 and 2.30ish. You’re supposed to swallow it with water but I find it more convenient to just pop it under my tongue and let it dissolve if I’m out and about (I always carry some in my handbag).
That’s probably enough for now so I won’t witter on any more! I hope this has helped ?
