I have bumps on the back of my throat and my tonsils seems to be swollen?

I recently noticed I have bumps on the back of my throat and my tonsils seems to be swollen and have signs of puss . The doctor took a strep throat test but it came back negative and never gave me any information further then that so I’m here for a second opinion. Sound I be worried/ concerned? What are the possibilities of it being.
