Suggest Remedy For Throat Pain

Hi I am 29 yrs old youth and I am having the throat pain since 3 years. When I went to the doctor, he said to me that I had Gastric and that is being created by the virus named H-Pilary. He gave me medicine and I tried it for a year but still the problem is not solved. I also have the problem in standing up fora long time. What can I do?
