U need a urinalysis: You certainly need to see a doctor. Allowing problems to persist for months will put you at risk for permanent injury. If someone were to tap on your left back just below the ribcage and it causes a sharp pain then you likely have a kidney infection which is very serious. Even a simple urinary tract infection (UTI) should be treated. See a doctor or go to the ER and get a urine test.
