Hi. Thanks for your query. Noted the history about your Mother and understood the concerns. The hard burns on inner thigh, buttocks and labia can be multiple developing abscess that some have healed but the ones on the buttock being subjected to pressure can not be controlled without proper investigations and prescription based treatment. Hence I would advise you the following: Burns caused thus should be be examined by the Surgeon or Burns Specialist for clinical evaluation and investigations. Fouls smelling is usually due to infection hence the wounds need a local treatment with Hydrogen peroxide, Liquid povidone iodine and oral management with an antibiotic and anti-inflammatory medications.
