I'm just wondering if anyone else with hypothyroidism is experiencing muscle fatigability? I have been getting slowly ill over the past 10 years... the usual symptoms of crushing fatigue, brain fog, weight gain,, gut disorder, migraines etc.... but 4 weeks ago (before the fatigue made me pretty much house bound) whilst out on a walk with my partner and kids, my legs collapsed beneath me in fairly dramatic style. I've been reading up on the different types of muscle weakness, and the best description is 'fatigability' rather than muscle weakness.
The first, say, 50 steps are normal, then my leg muscles will start to feel woolly and fizzy and I know then I have a limited amount of steps before my legs collapse.
Rest helps. So, I can eat them be able to walk again as soon as a few hours later. I have started to feel marginally better after starting levo, but my middle symptoms remain the same.
My gut feeling is that it might be a 'co-condition' of some sort. Myasthenia Gravis fits the picture, apart from having no eye symptoms. I don't know if Adrenal fatigue might be causing it (undiagnosed as yet)
Any suggestions as to what the cause of this might be would be gratefully received, as its a distressing symptom and affecting our lives as a family greatly.
Thank you! Xxx
