5th metatarsal region hurt back in Feb. I took 15 days off, got mri, it was clear. took another 11 days off because still sore. ran one mile a day for a week, calf hurt, took another week off. then, over the course of a month, slowly built up to 4 miles, foot uncomfortable but not painful. then this week, 5th metatarsal head (where metatarsal meets pinky toe) became super painful, mainly when first waking up and walking barefoot in the house, but pretty much all the time. plan on wearing boot and no running until i see podiatrist in 10 more days and then hopefully i can get another mri within a few days after that. i'm just wondering, if it is a stress fracture and already in the healing process (fingers crossed) will it show on the mri??? i wonder if that's what happened last time?
