There is some evidence that other auto-immune diseases may come along with the Graves’ such as Rhuematoid Arthritis. Many of us have those aches and pains, with me it is my upper body and arms. Your doctor should test you for this stuff, mine did recently although the beginning stages of rhuematoid may not show up in the tests for a few years. Mine were negative but he suspects it anyway. You should probably be checked for fibromyalgia, etc also on the very slim chance one of those is affecting you.
I just moan and groan a lot, then laugh about it! Really funny tho, when I’m rock climbing, the pains seem to go away. Fear probably takes over!
