Actually the help does not go into injuries or diseases in detail, and this is one of the more detailed injury and disease models around in this type of game anywhere.
Injuries are many and varied (over 200 different ones) and each has a different scale of possible severity and duration. Diseases (over 270 different ones) are many and varied too, with different possible incubation, severity and duration ranges.
The primary difference is diseases can sometimes permanently affect stats in a negative way after they go away, depending on the disorder (the "scars left behind", so to speak).
What's the chance of a warrior dying during a match due to potion use? The reason I ask is because in less than two seasons I have had two warriors die due to chemicals in their body and a third one die in a separate game. This was using the lowest danger (<10 in each case) potion. I can put up with stat loss and diseases or what-not through potion use, but the chances of your warrior dropping dead seem too high even consider using a potion.
Potion "intolerance" builds up over time, it isn't just based on an immediate use. So if you used a potion (even a weaker one) in 10 straight matches, it builds up an intolerance over time that doesn't go away right away after the potion expires (similar to the lingering ill effects of other real-life drugs, like steroids or heroin and the like). It's one feature that makes the game unique.
The percentage that the chance of future problems goes up is based on the strength of the potion you use of course.
