I'm pretty sure I have tendonitis in my foot, but I'm not sure which tendon it is so I don't know how to treat it. It's tendon running along my inner foot to the big toe. I think it's tendonitis because when I press it it's painful and makes a crinkling sound. I rested yesterday and ran 5 miles today with very little pain. I've been icing like crazy. Anyone know what tendon it is and if I can run with it?
