Well, I am that person who don't like to go to hospital. Sometimes it was a little hurt and I thought maybe I can check it on the internet to find out what's wrong with my body. I believe that no one can know my health more than me. So I always surf the internet to find a method or fix. And I found this site. Very convenient and quick. And it's reliable as well as professional. So 5 stars for you. But I think that if you're really sick, you should go to a real hospital.
