Help?

I'm a cutter and while I am working on it, I have some pretty fresh cuts on my wrist and my leg. The wrist is no problem, I can just wrap it and wear long sleeves, but I work at Target and we have to wear khakis. The khakis always rub on my cuts no matter what and sometimes (even if it's bandaged) it really hurts and sometimes reopens the wounds. It's really only comfortable to wear sweatpants. I work really frequently and I just don't know how to go about asking my manager if I can dress a bit more comfortably, just until everything heals up. Any thoughts? ||| EDIT: Thank you for the support and advice, I'd like you all to know that I am recovering and I do see a therapist and it's something I'm working on, I'm simply asking due to my current situation. Self-Harm is an addiction of mine and I'm aware that it's not a good or healthy way to cope.
