I am new to the boards but saw your question and wanted to reply. I have a friend who had a hole in her ankle that would not heal...went to several doctors in Eugene/springfield Oregon and finally saw one that took a look at it and said he could have it healed in 3 weeks. My friend laughed out loud! But he said her problem was varicose veins that were keeping the blood and oxygen from getting to the wound. He stripped her veins in her leg and it was healed in 3 weeks...not saying this is your problem but might be something to look into.
