Knee Arthritis More Condition_symptoms Do You Think That I Have Any Knee Arthritis?

Do you think that I have any Knee Arthritis? - knee arthritis more condition_symptoms

Well ... Was about 9 years since I go the pain in my left knee. If I am not mistaken - that began when I was 10 years - now I'm 21 years old)
The symptoms were and are: stiffness and pain in the knee. However, there's no external injuries, and I felt as if something "needles" in her.
So far I have not been a doctor because my parents prefer traditional treatments such as traditional herbs.
But a few days ago I read about arthritis and even osteosarcoma ... Not bad, and yet there osteosarcoma:) But I'm afraid I think there are as rheumatoid arthritis ...

What do you think?
