When I apply pressure to the inside of my left foot, it hurts. I looked up the muscles on google that are in that area of the foot, and it looks like the Abductor hallucis is the one that's hurting me. There's no discoloration or visible damage or bruses, but it huts to apply pressure. It's been like this for about a week now, and I don't know what to do. I have no idea how I even hurt it. What should I do? Does this kind of thing just go away by itself?
