But I have all the signs and symptoms of hypothyroidism except for the a fib! I am tired all the time. The skin on my feet is cracked and bleeding. The meds that the doctors gave is methimazole 10mg which makes me feel worse than I already do so I have not been taking it! At least I can function but when I take it I feel like I can barely move! What should I do? My husband and I are planning a trip to North Carolina to see our son in the next few weeks so I do not plan on doing anything till I get back.
