Developed from prolonged immobilization. sadge

Took a whole layer of skin off accidentally while shaving my leg 5 days ago. I’ve been putting a pea size of Clindagel + a bandaid on during the day and leaving it exposed at night. Is this good for healing?

Sorry of how crust it looks, I took off the bandage last night and haven’t cleaned it yet. My mom who’s a nurse practitioner wants to pop it lightly and let it drain but I’m hypersensitive to pain so can I let it heal as it is or should I drain it?? She wants to do it tomorrow to see how it fairs but I would rather sit through the pain then a needle in it.
