I have a foot injury, probably from overdoing an ambitious balance exercise.....it's probably Plantar's fasciitis......probably. It hasn't gotten worse, it's even lessened a little bit, and I bought an elastic "sock" that helps the discomfort. My annual doctor visit isn't for another 5 or 6 weeks, but I may schedule it sooner and ask his advice. I can walk around OK, it's only just certain postures that bring about the pain and it isn't even horrible pain.......Maybe 3 on a 1 to 10 scale. But something's definitely injured in my right foot. However it doesn't present itself at all when I do my daily 30 minute cardio event on the recumbent stationary bike. I've discontinued my daily squat exercises though
