Possible strain : You may be dealing with a strain or plantar fasciitis. You can apply ice, stretch the area and use an arch support. If you continue to have difficulty consult with a podiatrist or orthopedist.

Tough to say!: Have you changed shoes? Socks too tight? Are you sitting in one position too long? Changed medicines? Eating too much salt? Overexercised? See a podiatrist or your family doc to sort out what's going in.
