Spider bite...should i worry?

i woke up the other day with what felt like a mosquito bite although it wasn't itchy or red so i simply just blew it off. it has started to bother me so i decided to take care of it myself (stupid i know, but i at least use alcohol and neosporin) and pop it. that was when i noticed two little puncture wounds and then the pressure caused puss to drain out of it, it is still swollen and hurts (although not nearly as much as before) and its turned a little darker, like its bruised but not much darker. should i be worried about it or just apply ice and keep the neosporin on it?
