I have been battling a problem when running with my leg, but before l go running or sometimes during the day as l walk around, l scuff the ground. It's mainly the mid section of my foot. Some days are worse the others. I can run fast up on my toes, but walking l scuff the ground. I have had a problem with leg coordination too,but l am not sure if this is leg drop. I went to a specialist and was told there was no weakness or any indication of that,but l am still scuffing the ground with my mid foot when walking. This doesn't happen everyday or all the time, but it's very annoying as well as confusing. What does this sound like? And l would appreciate any advice.
