Does anyone have swelling around their collarbone(not painful)? If so, what could it be? My right side seems to be a little more slightly swollen than the other, I've also had shortness of breath and I have this pain that goes up the side of my neck when I'm breathing really hard, the ER dr seem to think it was probably my muscles but never bothered to feel my neck or even look at it much less. I'm on Imuran/Plaquenil but I don't think those med's would cause that, I'm thinking it's related to SLE???
