Sorry. I realized that too late I am new to this! Thanks for your answer!
Hi. Not sure why you posted on the MS Forum, unless it was your mention of MRI. However, MS is a disease of the central nervous system, which is the brain and spinal cord. Some MSers do have foot problems, but due to demyelinated nerves, and not fractures or marrow edema.
This is really not the place to ask, but I see that MedHelp does have an Orthopedic forum, so you might try there. Good luck.
