Infected finger becoming numb?

I’m 15 and I’m from Texas. I only take medicine for my allergies with IS Claritin. I let my finger nail get long and I think it grew a little bit into the side of my skin. So when I cut it, I didn’t notice anything on my finger except a sort of hole or separation between my skin and fingernail. I put some antibiotic ointment on it, washed it and put a bandaid on it but every time I touch it or accidentally bump it it hurts like crazy. I took off the bandaids just now and there is a red bump with yellowish clearing stuff coming Out. There is the same yellowish goo on my bandaid. Also my finger is a lot warmer than my other fingers. Just today did my finger start hurting without me touching and is almost completely numb.
