For about 2 weeks I keep having a red patch followed but itching. It only appears on my body. My neck and back mostly. I was doing laundry and all the sudden I felt the itch coming on. I told my husband to come quick and take a look before I start scratching. All that was there was a big red patch on the top part of my back. He scratched it for me and put benadril on it and it stopped. Then all of the sudden while we were still in the bathroom I got another one on my front shoulder. This is weird what is going on.
