I also get a tingling in my foot. The pain comes and goes; the longest and worst case was on and off for an hour - it was like a shooting sharp pain deep inside. The tests described above came back negative. Do you think this could still be shin splints and would I need an xray to determine if its such? This has been going on and off for a couple years and the pain is so excrutiating that I was brought to tears already by it.
