How did this happen?

I am looking for any and all medical opinions. Even from the mystery political commentator on Hillenblog.

I woke up Tuesday morning and could hardly walk on my right foot. There is a shooting pain in and below the bone in my arch and it is radiating up the back of my calf. I can put some weight on it ( probably more weight if my weight loss plan had worked), I can't stand on it alone, walking is extremely painful and Jackson says that I go up the stairs like a baby. There is a little swelling and the area is red.

Here is my weekend.

Saturday- Hiked 7 miles and went caving. Felt fine
Sunday- Church and played water volleyball. Felt fin
Monday- Played washers and ate. Felt fine
Tuesday- Woke up and felt like someone ran over my foot.
Wednesday- Same as Tuesday

What do you think?

If it still hurts on Thursday I am going to the doctor. So whoever guesses the correct diagnosis will get a prize.
