I've had my characters wounded and imprisoned countless times and usually it's a fun little experience that lasts 1-4 days, perhaps more during imprisonment if your char can't escape.
Recently though I had one of my characters seriously wounded and slipping back and forth to wounded and seriously wounded for several days. It all lasted about a week and I think devs did something to pull the char out of this loop, if they wouldn't I think it would be infinite loop effectively locking my character away forever and ever. Of course I reported it.
