Signs of healing for me were no more huge crusts, no more hardening of the skin after that last crusts fell off, a HUGE decrease in inflammation. Over three months I could see them getting better and better in terms of inflammation. There would be less and less. Sometimes I would wake up with some inflammation but it would go away as the day progressed. Eventually there was never any inflammation at all. They also no longer felt raw, they no longer had that slight burning/hot sensation.
