I'm now almost 4 mo post plantar fasciotomy surgery: at 3 mo everything had been feeling great for about six weeks - I stand at work (teacher), go square dancing a couple times a week, work out three or four times a week (classes like cycling, pilates, yoga, hand weights, squats, abs, etc.). Then all of a sudden I woke up one morning and couldn't walk---my foot felt like it was cramping so much!!! I hobbled around all weekend, then decided to put my boot cast back on. I basically couldn't take a step rotating over my toes, or I'd get severe arch pain. A week later at my podiatrist appt he just told me to expect these setbacks over the next year or so....So I'm walking slowly, stretching my foot, little by little it's getting there. It's been just over two weeks. I'm maybe 80% back to normal., but my foot grabs me randomly and feels weak. I tried modified exercise classes and square dancing again this week. For small steps all around my classroom it's OK-- but when I start taking longer steps faster down the hall to the restroom, I have to go slower or there's some pain. Hoping to be walking fine for a trip to India this summer....I thought I was out of pain stuff after the surgery had healed up so well...I guess I should have taken it slower??
