Searched: various combinations of ligature + strangulation + signs + symptoms + hoarseness + recovery
The main character in question is a boy, around 11 or 12 years old. He's been strangled with a cord by a boy a few years older than him, though the strangulation attempt was interrupted before serious damage could be done.
I read that in most cases, the victim doesn't show significant signs of having been strangled, but I'd like it to be more obvious in this case. The problem is, I don't want to hurt him too badly. He is not going to receive any sort of medical treatment and has to 1) survive and 2) have no effects lasting into adulthood. (No permanent voice change, no brain damage, etc.)
I was thinking of going with petichiae, bruising on his neck, and having his voice be hoarse, but I'm not sure how plausible this is.
I'm particularly worried about the last part. I've read that a person's voice can be hoarse after strangulation, but I'm wondering if that only occurs with more serious damage and how long it lasts. I can't seem to find much of anything about recovering from hoarseness after strangulation; at the same time, I can't find anything that specifically says the hoarseness would be permanent, either. (My google-fu is weak.) If the hoarseness would be permanent or more dangerous than I'm looking for, I can drop that easily.
So, little_details, what do you think? Are my signs alright for this, or too much? Would hoarseness be permanent (or signify more serious damage)?
