My doc didn’t tell me about the Balmex tip I told him and gave him my procedureSeveral years before that I had a couple tests one of which was an x ray and they both requied the puge...and it hurt..well I began to think about diaper rash and how babies feel..so I thought...let’s give the Balmex a try...it worked. The doc was glad to get it my tips and has passed it to his patients. Use the stuff liberally..really glop it on..any shield between the delicate buttinsky skin and the fluids splating along..makes things go better.
