I'm sorry but you won't recieve any professional medical advice here or any where on the net. That's just not done.
Medical care even when your there in person is not one hundred percent accurate.
Yes, you should have told your doctor everything. Yes, you might have influanced his diagnosis. And yes, you should go back to see him as soon as possible.
If you are in acute pain, you could go to the emergency room of a hospital. They can inject a dye and using x rays or mris to determine if you in fact have a kidney stone.
Peace
