I have been feeling ill for about 2 weeks now heavy legs and arms and fuzzy head pressure in the ears and very fatigued even after loads of sleep. Is this thyroid related? I take 50 mg levo a day. Last week my bloods showed tsh 4.2 and doc said that was normal... I took a 75mg one day and 100 another just to try feel better but unfortunately nothing making me feel better... I have a 10 month old son I have been off work sick this week and it's really affecting every part of my life. I only got diagnosed in pregnancy last year which makes me think should I be on the medication at all? Any help really appreciated.
