Open Question: who should i see with joint pain?

I really do not waist joint pain – in my left side, knees, shoulders and neck. My doctor is not interested, but said it was arthritis and pain medicine to me laugh out loud! What do you think strange is that it is all on the left? I do not have xrays or any other – Sugar said, no problem. I went back to him and the blood test requirements, but he again said there was no meaning. Do you think I should see a ridge or osteopath or physical therapist do? dont have to waste money, but I am only 47! Which is best?
