I've had this exact occurrence a year go, my larger female develped white spots after a shed. They eventually scarred over and I ended up putting an antibacterial cream for about two weeks as well as prescribed shots every other day. Make sure your enclosure is well ventilated and the humidity is around 60%. Go ahead and get some antibacterial cream and apply it to the spot reguarly, if it begins to scar over (it would look like the scales are drying out) then I'd reccomend a reptile vet. I hope your girl makes a well recovery!
