I have pain in my foot that I don't entirely understand. At first, after doing some research, it sounded like posterior tibial tendinitis, but I'm a little young for that. It hurts in virtually the same region, though. The pain begins in an area in front of the ankle and continues along the line of my foot, I guess along the arch. The pain comes and goes, but is pretty severe after a long day of walking or standing. I went for a strenuous walk yesterday and today the foot hurts extremely and is swelling a bit.. This may be an absurd detail, but I feel a little bit of relief when I place the arch of my foot onto something hard..
