I ve been taking Levothyroxin and have developed pains in my legs, I told my Dr. if I might need to change medication, he said no....pharmacy stated they would give me Levothyroxin made by another company....tried that for 2monts, leg pain was so painful it became hard to walk...talked to my dr again, he stated He believe the pain was in my head...I couldn t believe it, however that is what he said..can Levothyroxin be the cause for my pain, or do you too state it is in my head.
