I've been trying to shake off the health anxiety bugbear for a while. Earlier this month I was having pretty bad chest pain so I actually went up to the E.R. where they found nothing. At the same time, I had been having on-and-off pain in my left shoulder but it seemed like a secondary symptom, and during the commotion of the E.R. trip I forgot to bring it up since it wasn't hurting at that particular time.
When it hurts, it feels like the muscles around my left-side collarbone, shoulder, and neck are all seized up. Being away from home with the pain really bites because it interacts with my anxiety in a big way and makes it hard to walk around because of this weird pulling sensation, like there's a string between my upper left chest and my head trying to pull them together until my head is squashed down against my shoulder.
I was looking in the mirror, palpating the area - which I know is classic HA behavior, but I just wish I knew what this was - and it seems like there's a raised lump about halfway between the left side of my neck and my left shoulder. There's nothing like it on the right side. The lump goes from the top side of my 'shoulder blade' area to above the left side of my collarbone. It's not hard or discolored or anything. Instead it feels just like normal skin. Sometimes I wonder if it feels a bit warm to the touch, but that's probably all the icy hot I've been putting on it.
I worry it's a lymph node or something, but if I remember correctly from school (I've been trying not to google), lymph node problems are usually accompanied by other symptoms like fever and chills and stuff. All I have, besides the pain, are anxiety and some fatigue.
Anyway, I thought I'd ask here instead of googling. Thanks, everyone.
