Maybe the ones that need to be toned up are Stab/Concussion/Cut/Burn/Acid Burn and Frostbite.

Ear Injury needs to be nerfed on its gimmick. Maybe making it so the text's font size is forced to be reduced to a smaller number like 1. It's a roleplaying game. Mechanics don't need to dictate 100% of what you perceive or not, imo.

I don't mind a cold ending in someone being treated as over encumbered, since that's what you get for not treating them in time. But maybe making your character sneeze from time to time, to show off that they're not feeling so hot is also a good deal.
