My daughter has been ill for nearly 3 months with fatigue, sleeping a lot of the time at first but then seemed much better after a couple of months and was starting to do some walking and less sleeping. She then started having tremors in her legs which were horrendous, lasting up to 3 hours at a time and several times a day. She was given Diazapam and then Baclofen to try and control them but they weren't working. In desperation, I tried an intensive magnesium, B vitamins and CoQ10 supplement which amazingly seemed to do the trick! She has been able to walk and do more things in the last week. We are waiting to see an endocrinologist and a neurologist but I wondered if anyone had any advice. I suffer with chronic fatigue and fibromyalgia with normal TSH results but my T4 was 12 and my doctor let me have a trial of thyroxine 18months ago with great results. My daughter's TSH was normal and T4 was 14.5 but her GP wouldn't let her have a trial, despite many more symptoms of under active thyroid than me. She has suffered with mild fatigue for years and has developed more symptoms of under active thyroid over the past year. Thanks.
