I‘m on spur side with the Far Cry games. They feel like checklists to complete rather than good games. FC3 and Blood Dragon were the only ones I truly enjoyed, and FC4 being the only other one I even finished. Albeit I finished it within. An hour because I actually did nothing until that dude come back lol
I don’t know where you are, but if you’re in Europe I’d get my hands on some Novalgin (illegal in the US because it isn’t addictive) other than that there’s some kind of pads for jaw operations that you put in the freezer.
I personally find pain more bearable than the cold, so no ice and a lot of sleep for me
