I have a lot, I mean severe pain that shoots down my foot from abou the middle of the foot down inbetween the 3rd and 4th toes. It is sharp and doesn't last long and occurs mostly when I am walking. I have had surgery (10/1/11) on that foot with a consequent MRSA osteomyelitis infection afterwards. I thought maybe the pain was from that, but this is different. It is intense although brief. How can I tell if this is what it is and what is the treatment for it? Does it require surgery? What kind?
