A minor wound usually can be treated at home. Keeping the wound clean is the key.
Wash the wound regularly, such as one to two times per day, and apply fresh antibiotic cream and a clean bandage after doing so. Antibiotic cream can be found over the counter, usually in the same section where you would find bandages. Continue this cycle of cleaning and covering the wound until the wound closes.
If the wound is painful, over-the-counter (OTC) pain reliever medication may help. Always check with your healthcare provider before starting any new medication.
