I have a third degree burn on my leg that is untreated. i've kept it clean and aired out. it is now thickly scabbed over, is that ok?

Burn: Apparently it is ok, as long as there is no pus and no surrounding erythema, but if you see pus , you develop fever, pain, increasing redness around the scar , you will need to see a doctor.

Maybe not OK: If you truly have a 3rd-degree, or full-thickness, burn, unless it is very small or narrow & can heal in from the sides, it will need to be skin grafted to fully heal it. Partial-thickness (i.e., 2nd-degree) burns will heal in 1 to 3 weeks. If your wound is not fully healed after 3 weeks, you should see a general, plastic, or burn surgeon.
