I am also interested to know because I also have pain in my chest on left side and under left breast and in middle of chest towards collar bone, we believe I have Hashimoto's but am not on any Meds as of yet! and enlarged thyroid with large nodules (waiting for FNA)
I'm also interested. I get pain sometimes in my armpit, shoulders, and upper arm. I have Graves and was on antithyroid meds.
Hi,
I'm intersested to see if anyone else has this same problem. I have the same type of pain but on my right side. It started in shoulder blade and now it has crept forward and down my arm. My ring finger and pinky get a little tingly and my elbow also starts to hurt, but the chest and armpit thing cause me angst because that is where lymph nodes are. i had an MRI for the shoulder and also a baseline mammogram and all came back normal. I have Graves Disease and had RAI about a year ago and I am now on .112 Synthryoid.
