Synthroid and muscle weakness

I wouldn't give anyone ant medical advice if I thought it did not work for me. For anyone who has the side affects that follow from taking thyroid meds:itching all over, muscle weakness, heart palpitations, extreme fatigue, joint pain especially in the lower back, clicking in the knee joints when walking, feeling like you are staring(in a trance), mood swings, etc... Please talk with your doctor about APO-NABUMETONE. It is for inflammation/pain. Since two months I was prescribed it , I have no symptoms. If I stop it the symptoms come back in two to three days. I am aggressively pursuing answers to why these symptoms happen, and I have tried every thyroid drug, just recently natural Thyroid. They all produce the same symptoms. My question is whether or not any endocronologists read these forums and if so do they think that our symptoms are just in our head as my doctors do. Thank you everyone for posting because now I don't feel so alone, I am not the only one.

Has anyone out there experienced leg cramps or a feeling like weak muscles in your legs?

stomach cramps, diarrhea, headache and muscle weakness and fever. I have been on this medication for two weeks.
