I am 52 years old. I am a contractor and buy with my construction work. Unfortunately from last 1 year I am suffering from osteoarthritis. I am having pain below my right knee. I can't walk for long distances because I get pain below my knee. Six months before I started to take parijata devotion daily in the morning for 45 days. After that the pain reduced to some extent but not completely. Kindly advise what I have to do to get rid of the pain completely. Thank you.
