I have a rash on my arms....very itchy! Remembering getting this before a few yrs ago. My Dr. back then, during my appt., came back into the room with this little bottle of cold (out of the fridge) worm water. I had never heard of it. He then wet two paper towels, poured the solution on the wet paper towels and placed them on my arms and they brought instant relief. The rash quickly went away after a couple more applications. Is there an over the counter solution like this to help me? My then Dr has since retired.
