Have been practicing Tai Chi for about 8 months now. Shortly after started (dunno if coincidence) one pair of shoes that I had really started bothering me on the top/side of my foot right in the area of the ball of my foot. It almost felt like there was a bruise, but I could see nothing. Eventually, it felt a bit numb and tingley.
After dealing for a while, I bought some new shoes and the pain of this subsided substantially. However, whenever I am wearing shoes of any kind, I can "feel" the area annoying me, although it does not hurt badly at all. If I rub it, again, it feels like there is a bruise way down but there is visibly nothing wrong. If nothing is on contact with the area (even while practicing) I feel no pain and am not even aware of it.
Any thoughts?
