I Had My Baby And Then About 4 Weeks Later

I had my baby and then about 4 weeks later when my period was almost over i scratched down there in the shower a lot and realized when i got out the shower that i had scratched a good bit of skin off :( it has been about 2 weeks and i still scratch sometimes cuz i just cant help it but i dont plan on scratchin no more because im sick of this. Ige tried triple antibiotic ointment and it does really seam to do much. Any advice? What can i do to get it to heal up?
