Body burning sensation and joint aches.

I'm having elbow and knee joint pain and burning sensation for the last 2 to 3 months. I don't feel the pain while walking, it generally happens while sitting only( it's feels like someone is applying ice from inside my knee joints) apart from that get burning/tingling sensation all over the body at regular intervals. Mostly on the thigh and upper arm muscles ( above arm joint ) , sometime feel needle pricking on fingers tips and on feet's. have done complete body checkup and the results show up normal only. I mostly feel this burning sensation and pain during office hours( sitting in the AC). Because of the pain it's really very hard to concentrate on work because it pains really bad on the knee joint. Also get the same burning/ tingling sensation on private part( penis). I would like to say that bacteria was found in the urine test( 4 months ago) and it didn't show growth in culture test. Could you please help to suggest what should i do now ?
