Hey, After nearly 6 weeks of training in ninjutsu, I haven't been able to get rid of this constant ... discomfort (?) on the top of both of my feet. It feels sore and bruised but there is no swelling, inflammation or visible bruising. We always stretch thoroughly at the start of every class including ankle and foot rotations but when we sit in seiza position, your feet are tucked under you with the top of your feet faced down and your toes faced somewhat inward. This is the traditional stance when sitting down. We have the option of positioning our feet differently if we feel too much discomfort but I personally like it. After a few minutes, my feet tend to numb up and oddly, I enjoy the sensation. However, every time I rotate my feet and my ankles for the past several weeks, I feel some discomfort at the top of my feet as if they're constantly sore yet only feel it when I sit in seiza or do ankle rotations. I am fairly confident it's either the tendons or ligament and not the bone, muscle or nerves since the pain doesn't shoot up and I know what it feels like to have broken bones. While it's not bad enough that I take pain killers for it, I am worried that I may injure it if I continue to apply the same pressure to it. Is the pain simply just my feet getting used to sitting a certain way and stretching my feet in an odd way or is the discomfort something I should take more seriously? I also don't have health insurance at the moment so I'd like to be a bit more cautious than normal. I'm only 28 and my bones are pretty tough so it's not arthritic in nature. I attend class 3 times a week. Has anyone else experienced this? Please provide some insight.
