Levothyroxine uses answer the question only please.

I'm 20 years old and been on levothyroxine all my life because I was born without a thyroid. I'm a right pain in the arse taking my tablets but with my level been sky high last time I had a blood test I've stuck to them and not even missed a day, I'm on 175mg a day. My question is does anyone get really really bad aches a pains in their bones? I'm getting them really bad on and off all over my legs and arms, I know it's normal to get it when not taking the meds.. All help will be greatly appreciated
