I have a character who's suffered a gunshot wound to the side and reasonably serious blood loss. It's a little bit vague, so I can fiddle it to work. But, what I need is for him--after some time--to be functional (able to walk around and do relatively light tasks) but still have the injury and/or blood loss after effects give him enough trouble that he can't do strenuous activities like running or fighting.
I basically need him to be 'helpless' enough that he can't get away from a group he would otherwise leave, but at the same time still be able to be somewhat useful.
My question is, how long can I use pain and fatigue as a way to limit my character's abilities? Or is it a case of once you're up, recovery is quick?
If wound severity requiring surgery is necessary for this, I can do that, but afterwards it's a bit of an on-the-run situation, so care isn't great.
Can I use complications to buy myself time? For how long could they be a risk? I'm thinking infection, maybe re-injury from over straining? I don't want it to be super serious, though. Just to basically function as a hobble.
