My muscle weakness started about a month ago along with the massive joint pain. I haven’t been able to get it to subside yet, actually it appears to be getting somewhat worse. We have adjusted my methimazole doses, but that doesn’t seem to be helping so far. I am sorry you are experiencing this. My endo said that it was do to my numbers dropping toward hypothyroid and just has me taking naproxyen for any pain associated with it. Not sure I was any help, just wanted you to know that someone was having the same symptoms.
