Depending on where you are, a first-aid kit should be easily accessible. Ask someone to grab it for you while you begin identifying your symptoms and treating your wound. Items found in the first-aid kit that will be most useful to you include:  Gauze Wound cleanser (hydrogen peroxide, alcohol wipe, soap) Tweezers Pain killer Antibiotic ointment Band-aid Having a healthcare provider evaluate and treat your wound(s) is not a bad idea. Not only will you be treated by an experienced professional, you will also reduce your chances of infection and other complications. A treatment plan with instructions and recommendations will be provided to you based on the provider's assessment. If the closest facility requires at least a 10 minute drive, you should first obtain a first-aid kit and control any bleeding before transporting. This is your safety net. Call 911 in any of the following situations:  Penetrating wound to head, neck, chest, or abdomen. No access to a first-aid kit or medic station. Symptoms of allergic reaction, excess blood loss, or venom intoxication. History of prior medical conditions and/or medication use that may influence the wound treatment. When in doubt, confused, inebriated, obtunded, insecure, scared, or anything else you can think of.
