I Was Recently In A Forklift Accident That Degloved My

I was recently in a forklift accident that degloved my left foot therefore i had to get a skin graft. After the surgery everything went well, i got discharged and got sent home. Now... my donor site (left thigh) seems to begin a unbearable itchin sensation when i stand up and lay my left heel on the ground, and the only way i stop the itch is if i curl up my leg to where my knee is up pointing at the ceiling. My question would be if theres anything i should do, or anything i can do to prevent the itching sensation from my donor site?
