I have two spider bites on me from the last trip. Just found them today. They are swelling and red, i feel there is no reason to panic. Not sure what spider bite me. Have you guys been bitten from a spider? Also you can see the two tiny holes in the skin were the spider bite me, the holes are black, look like dirt. the only thing i think there is to worry about is infection, have heard spider bites often lead to pretty bad infections.
