This is serious, the man might have even gone through all the churches he knows thinking it's spiritual attack not knowing the cause. I had similar case when I broke my hand incidentally, after 4 months of the incident, I started feeling pain on my joint without knowing is internal injury. After so many months of try and error, I went to the hospital for proper examination. The doctor said I had internal injury. I thank God At the end of the day, it was sorted out even though I spent a lot of money. I hope He also gets better.
