I realized these lightening strikes weren't happening until I walked into an air conditioned room and removed my shirt. The fresh air was like walking into a sewing. contest. After an hour or two of "man-crying" I was desperate for a solution. I jumped in the shower, turned up the heat and instantly the pains subsided. I believe they are damaged nerve endings either healing or drying out...either way the hot water provided some relief. When the hot water started to cool I hopped out, turned down the AC, put on a scratch y shirt and laid in bed. Anytime it started to act up I would rub around a bit in the scratch shirt and the stings would stop. Im actually suffering from it as Im writing this post. Im hopeful this will help someone the next time they experience this awful sunburn sensation. It no medical remedy....but definitely provides some relief!
