Welcom Xakka. I am, sadly, a new expert on foot injuries. I tore my achilles and my plantar fascia and it took me over a year to be able to walk again. (I did a really good job) Those tendons are delicate and easily reinjured. Since they are so small, and have limited blood supply, they get scar tissue easily, and then don't reattach the right way. If you can manage it, I would see a physical therapist. They can help now and show you how to prevent future injuries. Also using inserts in your shoes can help. I had to experiment with several kinds and kept changing them out as I healed, starting with cushioning and moving toward more support and control. I also couldn't wear shoes, especially with a back on them. Wore soft clogs. You need to learn when to warm it and when to ice it, and you should not take advice on exercises. Sorry, especially since I know so many. But it depends on the exact nature of your injury and the strengths and weaknesses of your whole foot and leg. ie, I had to do stretches for my calf and hamstring because that had pulled too much on my foot. Who knew? A physical therapist could help with that, if you find a smart one. Good luck with it.
