About 5 months ago, after no specific injury that I can recall (though I step on kid’s toys and mega blocks all the time), I started getting the feeling that parts were moving around in the region of the 4th metatarsal, in the area of the toe joint there. It is not classic “popping,” but when I put pressure on the foot attempting normal walking, it feels like tendons or ligaments in the area are being forced out of the way, and other tissues are ‘pushing through’ — imagine walking on a bunch of parallel rubber gummy worms — they would move out of the way when pressure is applied.
