No, Lalaith, I don't know.
I had gone for a bike ride that evening, and did about sixteen miles in a local park, so there were plenty of opportunities for insects to get at me, or it could have been a spider, who knows?
I dismissed the bite at first, and then when I started having symptoms, I thought it was something else--something I ate or something in the environment. It wasn't until later that I narrowed it down to the bite, because I basically ruled everything else out.
It was very disconcerting, and the weeks that followed were no fun, because they used prednizone to treat the reaction, and prednizone has serious side-effects of its own, but I am all over it now.
