my mom got bit by one

I was bitten 20 times by a white spider while i was sleeping. I had a reaction and was put on a steriod for a week that took care of it. I had picked some flowering weeds on a nature walk and later took a nap in the car. I killed that little white bitch. It bit me in the face twice on my right arm 16 times on my right leg twice my left leg once and just above my groin once. my eyes and genitals became inflamed and everything iched. around my eyes the skin is still not back to normal. I hate spiders and caution everyone now. Keep your house and car well vacumed.
