A Pest Applicator called me and said he had a hobo bite on his cheek and wondered what he should do for it, we talked about the blistering and red circles and I told him without seeing it I wasn't sure.
The applicator is in the spider business and he felt sure it was a hobo.
The next morning he texted me that he had 4 more bites. I told him that was very odd but he was still sure it was a hobo spider.
The pain got much worse and he went to the ER only to find out is was shingles.
It does seem like every rash, blister, odd bruising; get's blamed on spider bites, but it is wise to let a doctor actually look at it and rule out any and all other possibilities as well.
If you have blistering it can be a reaction to a spider bite but be sure and rule out shingles as a possibility as well. Below is a good site for more photos and information.
