I have some questions before I resume training after a 2 year hiatus, I hope someone can help! I have always had bad knees, in the sense that they make a lot of noise when I'm in deep stances. However, I don't really feel any pain, and I haven't lost any mobility. Should I be concerned? Two years ago, I injured the ball of my right foot (big toe got caught on opponents gi.) Since then, life has happened, and I haven't been able to train. I figured this is good, it will give my injury plenty of time to heal. It still causes discomfort! I haven't lost any flexibility, but standing in zenkutsu-dachi for extended periods of time is fairly uncomfortable. Does anyone have experience with an injury of this type? Thanks in advance!
