My Feet Burn After Running. If It Is Nerve Damage

my feet burn after running. If it is nerve damage due to diabetes will my feet burn all the time. They only burn after running. I walk ever day and am training to run a 10 km race. I work out 3 x a week in a boot camp my feet don't seem to hurt then. I just started noticing that my feet only burn after a 5km run. I just changed my running shoes ( I change them often) I wear orthotics in my shoes. My feet are dry so I use moisturizer. Help i'm scared ...........
