What Can Be The Medication For Itchy Blisters After Taking Meth?

I recently tried meth for the first time(I feel like an idoit) and now I have what looks like pimples an blisters on my hands, between my fingers and toes, my feet, my arms and scalp an ears, some seem to be getting better but they hurt like crazy(mainly my feet) and they also itch really really bad. I know they're meth sores but is there anything I can do to speed up the healing process and stop the itching?
