I have a multiple marbel sized round lymph nodes in the middle of my armpit deep down. I had my covid shot in that same arm a WEEK,almost 2wks ago. I'm really worried. It's hard and moves around. Sometimes it hurts when I push too much. Is this cancer!? I'm really worried. I don't know if it was there before my shot. If it was from the shot why is it here this long later?  It's hard to feel unless I hunt for it bc it's so deep down.. I'm in my 20s and a girl. They feel like they move around when i touch them and they're hard. It is sore to touch a tiny bit. I can feel it when my arm is closed it's hard 

Theyre very moveable. It's hard to fully feel them because I touch them and they move all around
