Maybe taking a bunch of painkillers/having a Pain Editor should clear them entirely so you have a way of getting back into the fight quick. But you can already use drugs to boost your stats back up anyway.
I think a more productive direction for this conversation to go would be:
How can we better represent, both to the character with the stat penalty (I don't know what malususes means nor can I spell it) and to the characters who see that character, that they are still in pain despite their wounds having been healed and bones mended?
If my health message is anything below excellent, I don't worry about it too much. If It is excellent or better and I still have wounds (like bruises or cuts on @nakeds) that are unexposed or stat damage, I add an @lp to help describe my state to the outside world. Typically, this is straight forward. If my leg is bruised my @lp is 'limping slightly.' If my arm is cut my @lp might be "is favoring their left arm". If my abdomen/chest/back has a bullet hole my @lp is "wincing with every move." And so on.
I generally keep this message in place until both stat damage and the wound are gone. The problem is that I don't always remember to do this and I sometimes forget to take it off. I'm not saying that this is the best solution but I thought I'd share it in case it sparked ideas on an automated solution.
