I broke my fifth metatarsal about 11 weeks ago in what the dr called a 'watershed area'. Apparently the lack of blood flow to this spot has slowed the healing substantially. After 9 weeks in a fibre glass cast I've been in a walking boot for 2 weeks and schedule to go back to the dr for more x-rays in 4 weeks.

I was wondering if there were any techniques (e.g massage, magnets, hot/cold water baths, exercises) I could do in the meantime to try and increase circulation to that part of my foot and speed up the healing process?
