i am 69 yrs old and have started taking thyroid med levothyroxin this past year. it has been two weeks since i have had it. today my pharmacy told me that because i had missed the first two weeks that i needed to call my dr and let her know because it would mess up my lab numbers that are due to be taken. also i have been having muscle spasms in my entire body, my fingers, arms rib area, thighs, calves,toes, feet. all i have to do is just move the right way and i am drawn up like a pretzel. does my thyroid problem cause that? i didn t know that it would cost me. i don t have the money for the answer. i m sorry for taking your time
