Over the past week, I ve had a series of bites. About 10 days ago, I noticed two red marks on the side of my neck...thought they were hives (I occasionally get 1 or 2 for an unknown reason). When I woke up in the morning, they looked bigger and were raised up. These have pretty much resolved. The next day, I had two fang marks on the inside of the left wrist...like two pimples. They itched and oozed for a couple of days. Can still see the red marks but they have resolved. The 3rd instance was a red blister between 2 fingers, then saw my internist, who said it was a spider bites. Was really red and nasty looking the next day and my hand was swollen. I was on antibiotics anyway. The 4th instance was a 4 days ago. Its a series of 3 red raised marks on my face in front of my ear. They were about as big as a pea or small marble...just now going down. Had 2 pest control companies out....nothing found in my place but lots of small cellar spiders in the basement (live in apartment). There were 3 wounds this last time. Could it still be a spider?
