about 3 years ago I was told my levels were low and put on thyroxine a year later they had drop again and the same after.I have now been on a 125mg aday for around 14 months but think because of legs, arms etc bone(it feels like its deep inside of it) hurting,itchy skin and wanting to sleep 18 or more hours a day, sometimes I'm to tired to eat, thats why I lost weight instead iof gaining it as normal with underactive. So does this illness just keep on progressing or does it level out and stay that way. I hate it when my bones ache to the core and I can't keep my eyes open. I can't afford not to eat and I reallywould perfer to sleep than eat. Cook for thr family but I sleep instead of eating. So if any of you can let me know I'd be grateful.
