I've had a lump come up over the past day. At least I think it's only just come up but i only noticed it because it started feeling sore yesterday evening. I had a look this morning and you can see a slight swelling just under the skin in my armpit. It's sore to the touch and a bit painful when I move my arm up.
It feels almost like a boil type spot.
Obviously I'll be going to get it checked out at some point but other than the worst thing what could it be? I'm too nervous to google!
