I have had a spider bite once it was a brown recluse. I didn't think anything of it at first it just looked like a pimple. A couple days later it started swelling and building fluid underneath the skin. I popped it and it was very painful. There was greenish white puss and another day later it was more swollen the bite was on my inner thigh and by this time I couldn't even walk on my left leg. I went to a urgent care and they gave me a shot in my butt and said it was a spider bite. Look up brown recluse if you have something like this if you don't catch it soon you can lose a limb or they may have to cut around the infection in order to stop it from getting into your blood stream. I have had 3 of these and they leave a scar if you don't catch it soon.
