Note: This only works with pain pills (or if someone gives them to you). Find the water located near the location you get rescued (last stage). Before you summon the horde, duck underneath the water until you are incapacitated. Make sure there are teammates close by to save you. Let them help you up or give you pills if you need them, then use the pills under the water. Stand up after you use the pills and your health will go to up to 124. Note: This was done under the Easy difficulty setting.
