Pea Sized Lump In Throat Got Hit In The Head By A Phone And After Large Bump Went Down, A Small Pea Sized Lump Remained In Its Place?

Got hit in the head by a phone and after large bump went down, a small pea sized lump remained in its place? - pea sized lump in throat

I am 16 years old and a little more than one or two months, I was severely beaten on the head with a cell phone. It soon became a bit too much pain, and after a few days ago had fallen. I noticed a pea-sized lump in his place. The node is painless and I have no headaches. Is this normal?
