I feel burning when I pee and my kidneys kind

Patient: I feel burning when I pee and my kidneys kind of hurt. I have to pee constantly. Is it a uti or kidney infection? Also I don’t have insurance so I can’t go to the hospital without getting a large bill. I’m 20 years old. Can I get rid of this on my own?

Symptoms: Frequent urination, burning with urination, light pain in kidneys
