My fistula arm has been driving me nuts lately, its sooo itchy! I found this cream that my dad uses for itchyness and wow it really made the itch stop! Im not one for natural type things usually, but this cream really settled it. If anyone is interested its called Nature's Therapy First Aid Releif Cream. I bought it here
