Go run! It won't hurt you to run 4km at an easy pace (as long as you are overall healthy). I know plenty of people who run 8-10km per day six days per week for decades with no issues.

I'd go for a run! Just listen to your body and I think you'll be fine. You need the sleep.

I would go for a run if I were you. Just run veeery slowly and not a lot. Maybe even less than 4 km, and if you can, run on soft surface, like grass or trail or even track.

maybe swap it for something else that will help you stretch it out and be easier on the joints? Like swimming if you have access to a pool, or yoga?
I eventually went for a run yesterday evening. And this run turned out to be my best run in the past days :DThanks for the advice guys!
