I was riding bike and got stung by a yellow thing (most probably a bee) on my upper lip and I knew nothing about how I had to deal with the sting instantly. I reached home after 30-40 min and I saw my upper lip full swollen and is a bit red. It looks like swollen portion had some transparency in it. google and I washed it with soap solution, applied toothpaste 2-3 times for about 1 hour. I don't have much pain now but extreme swelling. What to do to get rid of swelling ASAP?
