I am 46 years of age, 5 ft 3 in tall and am in good overall health. Approximately two years ago, I was at the beach coming out of my room, located on the 3rd or 4th floor, I was stung by something and immediately turned around and went back to the room. The sting or bite was painful, swelling up to my knee. I was bit or stung on my left foot leaving a three-prong bite or sting mark on my foot. I immediately put benedryl creme on my foot up to my knee. Some of the swelling went down after an hour or so. But it was still painful and swelled. I was ok for the rest of the trip
