Humans naturally heal minor brute and burn damage, never heal from toxin damage

Split open your torso with a knife? Got crushed between a hydraulic airlock? Walk it off, worst case you lose some blood.
Got a welding torch to the face? Massive scarring from touching a live wire? You're back to 100% in no time.
Ate something bad and now your belly aches? Your body will NEVER, EVER stop hurting until you get medicine.
If there's any damage type that shouldn't heal it should be burn damage, which is a little lackluster currently
