Hey, that looks just like me when I get stung. That could be a picture of my arm. Like blueblood said, the sting will be warm to the touch. It's feverish. Blueblood is right about the location having a big impact. Ice gives temporary relief. Elevation helps some, but I think the poisons just drain to lower parts of the body. If I get stung on the ear or jaw the poisons just drain down my neck and it is all swollen. Within 24 hours it starts itching. The swelling starts to go down about 48 hours. In 3 days I am pretty much back to normal. I can't take Benedryl, so I just ride out the discomfort. I try to put a poultice on asap to help draw some of the poisons out. I have used turmeric and meat tenderizer with some success.
This is why I always suit up, even for the smallest of tasks in the hive.
