Ever have metatarsalgia or sesamoiditis?

Over the past 3 days I've developed an aching dull pan in that starts in the ball of my foot and goes into my big toe. I was able to finish my 9 mile run this am with only minor discomfort, but it is killing me to walk now (in hind site I should have skipped my run). After some basic research my symptoms seem to be falling into the category of Metatarsalgia or Sesamoiditis. I did do a hard hill workout on Wednesday which can put increased pressure in this area. For right now my plan is to follow the RICE therapy and possibly see a podiatrist on Monday to r/o a stress fracture. Anyone have experience with this injury and speed / length of recovery. I'm still 2 months out from my HIM but want to miss as little training as possible. Thanks.....Jason
