argh I so feel your pain! Mine is on the brink of healing, just a few mm now but it's been creeping so slowly recently. I feel my boyfriend says there are small changes just to make me feel better! My nurse used Inadine a few times before and it really seemed to help. We used it right before it closed the first time when I had a small ulcer. The iodine is mostly to kill infection but it seemed to help me heal. If it doesnt heal soon I may ask to try it again... Hope you heal soon!
