Oh my, I am so feeling your pain. Had a picnic bench my DH made out of 2 - 3" white oak fall over on my foot last year. Bench easily weighs 125 or more pounds. Thought I was going to die. Gosh that hurt. Thought it was broken, swelled immediately, goofy bruising, [i]indented[i/[ my foot the width of the board for a year, and to this day, my skin reacts goofy in that spot. Thankfully, nothing broken.
Lots of ice, elavation, rest, and meds for pain and swelling. Oh, and a nice soft slipper to wear.
