Itchy red bumps all over my back
I have returned from a trip to Fiji Island and South Korea, and while I was on the airplane on my way to the states, my armpits and back itched like crazy. After I got home, my wife says that there are small red bumps all over the itching area. I have trouble sleeping because of this itchiness. Can any one here know what this is? Might be an allergic reaction?
