It sounds like a spider bite if it is bruising in the area. Certain spiders can cause breakdown of blood vessels (bruising) you should see a doctor asap and make sure to note any symptoms. If the bruising spreads I would even go to the er even. If you are feeling flu like watch for this as well. Many people ignore spider bites, however they can cause serious harm from some and in certain people.
It could be many things as well, some people react differently to bites of any nature in immune response. However if this never happened before and certainly in case of bruising, get medical attention asap. Please let us know how you are doing.
Wish you well-kris I live in south florida as well. Many things here to bite you I found :roll:
