What is the best way to tend to a really bad wound at home?

Home health: Wounds require a team effort to heal. You can not treat a bad wound at home and expect it to heal.

See you physician: Wound care instructions should be obtained from a physician who has inspected your wound. Not all wounds are the same and not all will have the same treatment. Generally however, the wound site should be regularly cleansed with sterile saline or a wound cleanser. Deeper more involved wounds with signs of infection may require oral antibiotics. Consult with your physician for a plan of care.
