I Had A Right Hip Replacement 4 Years Ago And

I had a right hip replacement 4 years ago and from the time I left the hospital, they said I need synthroid, so I took it 25 mg. I could not recover, my left leg, had a limp, so it continues 4 3 months later. I cut the synthoid in half for a month, so that I could learn to walk without a cane. As soon as i go back to the 25, it effects my gaite. Thinking on getting Armor Thyroid, maybe this won't effect my leg muscles on the operated leg. I hate taking this I have gained weight in stomach and bust, and it makes me walk funny. I never had this before, what do you think?
