Was working in the lawn and felt the worst instantaneous pain I had ever experienced and couldn't put any weight on my left foot. Hopped into the house and put it over ice for about 30 minutes in excruciating pain. Had no idea what had happened but my first thought was Achilles. However, about 45 minutes after the incident, it felt almost normal and I was able to go on with my Saturday. Clearly it wasn't my Achilles. Fast-forward to Monday morning. I was on a work call and reached down to scratch an itch on my left ankle and it was swollen to about 200% of my right ankle. I took a quick trip to the ER where the doctor quickly pointed out the bite marks from the snake that got me. Must not have been venomous but it was REALLY infected. Put my on IV antibiotics with a second prescription and I felt great a few hours later.
