After our last e-mail exchange in March I extremely strictly followed all advice you give on healing sesamoid fractures (taping, orthotic, dancers pad, contrast baths and exogen bone stim daily, stretching, PT, shoe with stiff sole, Vit D and Calc. intake, strictly no running and no barefoot, and being careful with any activity that could put too much pressure on the sesamoid, sometimes Super Elevation). I spent and am still spending almost one hour per day with these treatments on the fractured sesamoid (I learned to do something in parallel...).
It was a very bumpy road since March and every other week I was near to calling my doc to get an appintment for surgery as I had setbacks and flareups (increased swelling, redness, pain, etc.) with the very slowly, gradually increased activity. However, every other day there was a tiny bit of healing which kept me going on and of course also the advice on your blog. Learning about good and bad pain and accepting some pain (in particular for people like me with no pain tolerance) is essential. I would say I did not achieve pain level of 0 (=no feeling of the injury at all) during day (rather a 1-2) but I was and I am pain free at night and when I get up.
