Anyone experienced that familiar sharp blister pain only to find no blisters on the bottom of their foot? During my 8 mile run Sunday and today's 6 mile run I started feeling like I was blistering on the ball of my right foot. However, my plantar skin is super thick and there are no blisters to be seen. If I press around on the ball of my foot I can feel where the internal blister is because of the sharp blister-like pain. It's not that bad and not enough to stop me from running but it doesn't feel great.
