A spider bit me, why the bite popped white stuff as it were a pimple?

because there is pus under the bite...the venom from the spider%26#039;s bite caused inflammation under the skin and the venom was deteriorating the flesh (or eating away at it).. It needs to be lanced and you need antibiotics or it may spread and worsen.|||infection|||u need to see a doctor bro|||The bite was probobly festering.Or it wasn%26#039;t a a spider that bite you. Or maybe it was a misqito. See when my brother get%26#039;s bitten by a misquito or a spider his bite does the same thing it does that because he is allergic to those bites. You might be too. I can%26#039;t really tell you about why your bite did that because you could have been bitten by anything and have any kind of reaction.
