I switched from a generic levothyroxine to Synthroid. After four...

i dont know what would be the cause of your pain. i am 25 years old. i have taken synthoid since i was 9 months old. i was born without a thyroid. so i have been hypo all my life.

synthroid has litterally saved my life. Actually i can say that i have taken levothyroxin as well...they did show any different side effects to me, but side effects are different for every one. the only side effects i show are simply the ones triggered my hypothyroidism.

so it could be the meds, or it could be something else.
just wanted to share with you....
later!
