16 year old near joint pain. need suggestion.? i'm 16 and i've been experiencing pain in my joint from time...

i'm 16 and i've been experiencing pain in my joint from time to time ( specifically my left knee and right elbow).

Whenever i put pressure on my left foot my knees receives a sharp pain.

And whenever i rotate my right arm i could feel the bones within my elbow move, almost like their grinding against one another. There isn't as much pain as my knee and not as frequent.

Its freakin annoying and im worried.

I NEED ADVICE.

P.S- money is restricted so an X-ray is last on my list of solutions. 8(
