To prevent bedsores, frequently change positions (every two hours), keep skin clean and dry, and use pressure-relieving cushions. For treatment, gently clean the area with saline. For mild redness, apply zinc oxide barrier cream to protect the skin. If the skin is broken, keeping it moist and protected with generic hydrocolloid or foam dressings promotes healing. Mildly infected sores may benefit from generic topical antibiotic ointments like bacitracin. Avoid popping any blisters, and please consult a doctor or wound care specialist to properly assess the sore and guide your treatment plan safely.
