Diagnosis Path: Diagnosis of a third-degree burn typically involves a physical examination by a healthcare professional to assess the extent and depth of the injury.

Long-term rehabilitation might include physical therapy to restore function and occupational therapy to assist with daily activities. Nail injuries might necessitate surgical repair or cosmetic procedures to restore the nail bed.
