Herpes zoster

Unfortunately, I suffered from the Herpes zoster,which is called as 帯状疱疹(taijyouhousin) in Japanese． This disease occurs only in people who had chickenpox, the majority of sufferers are more than 50 years old. And this suppression is more likely occur in people whose immune system is impaired due to aging,psychological stress, or many factors. This Summer break, as a charger of soft-tennis club (mostly I have worked as general manager) , I had to expose myself in the strong UV-light of the Summer. That's probably one of reasons I have suffered from this disease. Now it's almost cured.but in its prime time, I felt tremendous pain.I got a painkiller- pills,Anti-virus pills at the hospital. It was really troblesome days.
