Hi guys, 

Recently noticed where my arm meets my chest, like at the top of my breast before the underneath of my armpit, it’s very swollen and painful to touch. When I lift my arm up, you can’t feel any lump (although it’s still painful), but compared to my other armpit area, it’s very swollen. 

I’ve not been ill recently so I don’t think it’s to do with my lymph nodes, is it worth getting checked out? Or has anyone had anything similar?
