Hi sir, I feel like my kidney is swelling from inside. I just feel it for my right kidney. There is a lump also on my backside near kidney part, it sometimes pain sometimes doesn't, left side I also have the same kind of lump but small, I don't drink alcohol but I drink water very less trying to improve. No problem in urine. No pain also its just like I'm feeling that part is getting swallow, I noticed this few days back when my friend said that he had the same problem. After that I stated noticing it much. Should I visit a doctor.
