i train in MMA, but im not at a particularly high level. i was kicking the bag durring open gym. my technique and power are getting a lot better, but i still keep landing it too close to my foot. a proper kick should impact with the shin. this makes my ankles and insteps pretty sore, but its something you just have to put up with. it kept getting worse with every kick, and after a really hard one, i decided to stop kicking with the right leg, and just focus on the left leg and my hands. eventually i did the same thing with the left and just boxed for a while, before deciding to stay off my feat and get some ice. a hemotoma formed on my right ankle about the size of an egg. i took a month off, but when i returned i just hurt myself again durring some wrestling drills. after that it was about 3 months before i could even walk properly. it was 6 months before i had the confidence to jog or work out. its been a year now and i still havnt gone back to actual training, but im ready now.
