answer:Possible nerve damage. It makes sense to me that if he was digging around for that long that there might have been something damaged with the nerves in that area. The problem with your head is that everything is so interconnected that there’s a lot that can go wrong very easily based on one little thing. Hope its better and they figured it out. I got sick and my lymph nodes were so very swollen that I got shooting pain in my ear. There was nothing wrong with my ear, but it was a nerve that was being pressed on that was causing the pain. Its all connected.
