Spider bite or something else?

The day before yesterday I noticed a small pimple under my 4 year olds lip. I thought it was just a regular pimple from playing in the dirt. Yesterday it started to harden around the area and puff up her lip and chin. I squeezed it and some puss came out. Now the puffing is starting to puff around her cheek. What could have done this to her?

Squeezing a pimple sometimes forces the encapsulated pus (which is what the white stuff usually is) into the undlying tissues spreading an infection.

If there is still swelling it's probably a good idea to get her to a pediatrician.

Squeezed it?  Please get her in to see her pediatrician or emergent care asap if this has not subsided.

It could be an infection, maybe from a bug bite or something like that. But sometime after squeezing something it causes some swelling its the bodies natural way to protect itself. but i would take her to get seen , a 4 year old dont normally get pimples so it could be something your unaware of.

i dont think you have to worry. probably allergies....... or maybe a shower is needed
