During the past ten years of so, I have been suffering from a terrible headache. It seems to be getting from bad to worsethese days. Last night I got a sudden pain in my head. It was so terrible that I could hardly bear it. Although I swallowed all kinds of pain-killers, I didn't feel any better. It seemed that there was nothing I could do but phone for a doctor.

These needles may possibly do you some good."I agreed. In a moment, he had taken out a few needles from his purse. Without a moment's delay, he fixed a few needles into the skin on my head here and there. Before long, I felt thoroughly relieved.
