Yes, all that and a bit more. Bath frequently and wash cloths that contact the sore after a single wearing. A circle of moleskin around the outside of the reddened area around the sore and a gauze pad over that to reduce pressure. If the sore lasts several days or goes completely through the skin into the tissue underneath get thee to a doctor. I do health care for the elderly and an untreated sore like that can land the patient in a hospital for months and the caregiver in jail.
