Your blog is the best resource I've found for sesamoid injuries. Thank you for giving me hope.
This has been a frustrating injury. I am a female runner, 29 years old, and I went to a podiatrist after feeling some pain in my left foot during plank and downward dog in Pilates. After an initial mis-diagnosis, via an x-ray he found that I'd fractured one of my sesamoid bones. I went a month without running, but the pain didn't go away. I was even beginning to feel it when I walked up the stairs at work.
I decided to seek a second opinion, and went to see an orthopedic surgeon who specialized in feet and ankles. He did more x-rays, and advised me that my fracture was worse. He then gave me an air cast (walking boot), and advised me to see him in 4 weeks.
After 4 weeks in the walking boot, I went back to the doctor, and he advised me to try walking without the boot. After 3 days I was limping, and was in pain. This was so frustrating because the entire time I was in the boot, I was pain free.
I put the boot back on, and called the doctor. His assistant advised me to leave the boot on for another 4 weeks, and to then see him again.
It was durning the second 4 weeks in the boot that I found your blog. I was concerned that we couldn't really see the bones in the x-ray, and couldn't tell how I was actually doing. On the follow-up appointment with the doctor, I requested an MRI as you'd suggested in your blog, and had an MRI the following week.
On another follow-up appointment the next week, upon reading the MRI, the doctor advised me that the bone had healed, but that it had then necrotized. Looking at the bone on the MRI, it was darker than the other bones. What didn't make sense to me was that the bone would heal, and then just die.
I read in another part of your blog that bone growth can be misdiagnosed as necrosis on an MRI. Do you think this could be the case? Should I have a CT scan done? What is the difference between an MRI and a CT scan?
I've been in the boot for 2 1/2 months now, and still feel tenderness and some pain if I land wrong on my foot.
Thanks for all your help. Your blog is wonderful, and has really helped me understand what is happening with my foot.
