Side Effects from Methimazole?

Does anyone on Methimazole for Graves Disease experience moderate to severe joint and muscle pain? It’s mostly in my upper back and neck but lately its throughout my body like my hands, wrist, fingers, hips, knees etc. I can’t take the pain anymore. My primary doctor prescribed Indocin for me without saying much about it, correct me if I’m wrong but isn’t that medicine for Rheumatoid arthritis? I have yet to receive a phone call back from my endocrinologist. This has put me in the emergency room twice. Any advice would be appreciated.
