Hi.....I was diagnosed with AVN of the third metatarsal 5 years ago, which started off with a simple stress fracture in my foot.  I have had core decompression surgery, joint replacement surgery, and joint removal surgery.  Over the last 5 years, my foot still becomes very swollen, painful, and very cold.  The toe that had the avn, is unresponsive and curled over my little toe.  My fourth metatarsal is thinning out, very painful, and curling over....My big toe, I stubbed several months ago, and fractured to easily.  I have had 3 fractures in the same foot, over the last 5 years.  Any info would be helpful!!!  Thank you!!:-)
