shooting pain in knee

Hi there, i am 23 yr old male and have been suffering from a sharp shooting pain and burning sensation in my left knee when kneeling. I hear lots of cracking from both of my knees also and the other day at work my left knee was in pain when running and driving my work van also. Has anyone got any idea what this could be. I would be extremely grateful. Thought i would try this instead of going to the doctor incase im wasting time. Thanks
