During evening ministry time, I got a word of knowledge with vertebrae disks in the neck being popped out during a childhood accident, and it was never fully recovered/healed. An assistant leader of the village came up and said it was him. We prayed and he instantly received healing.
One of my favorite inner healings happened when a woman came to get prayer for the discs in her neck. I found out that this injury came from her husband violently beating her and now 15 years later she was in bad pain. I asked her before we (my catcher/interpreter and I) prayed if she had any unforgiveness toward her husband.
