Sounds like it was a bacteria.
No one has said if the woman spoke English, was she a new American, what kind of shoes was she wearing?
I was spider bit in my yard, in 2 days my foot turned as black as charcoal. At least this is what the ER doctors told me. I saw no spider, felt no sting just found the next day my foot was turning black.
All this was suppuration from the ER. Went in and had people coming in to look at my foot, only thing I could come up with was I was bare foot in the yard and everyone jumped on that as a spider bite. I could have run into something even in my house but I was afraid I had the flesh eating disease.
Interesting, no blood was drawn, just sent home with antibiotics that were so strong I received a yeast infection from hell. The black infection was not pain full, the Yeast infection was Lord awful,
the infection in my foot cleared up quickly, the Yeast infection just got worse.
I got stubborn as no one could tell me why my foot got black so I decided to self medicate for the Yeast. I must have eaten 20 pounds of active yogurt, even douched with it, yet I finally went back to the ER hardly able to walk. At this point the burning and discharges was so much people could smell me a block away.
One pill, what ever that was given to me in the ER cleared all that up, just one pill that I could have asked for when I was given the antibiotics.
Lesson learned, when given any kind of antibotics, if a female ask for the anti Yeast pill.
