I just came up with a very swollen and tender lymph node in my underarm. It has only hurt since yesterday morning. Is this something I need to have the doc check, or just wait to see if it will clear up pretty quickly on its own? I know I sound like a worry wart, but being diagnosed with mctd recently, I am not sure what I need to check with the doc and when... I sure don't want to waste the time or money- to see a doc when he will just tell me it will clear up on its own. Also, shortly after being diagnosed I have noticed I have what kind of looks like a rash on my upper back and shoulders but sort of looks like acne. I know-- it sounds gross, but the spots don't look infected like with acne... just red spots. It also doesn't itch or anything. Any idea what may be causing that? I have never brought it up to my doc and am not scheduled to see him again until December unless I have problems. Any help on these two subjects would be greatly appreciated. THANKS!
