I recommend that you:
1 - Drink a lot of water: start by keeping a small bottle of water with you all the time, take sips every few minutes.
2- Cranberry juice or tablets: proven medically to help in the prevention of recurrent urinary tract infections
3- Avoid too much protein in your diet (proteinsin big aamounts burden the kidneys)
4- Consult your doctor: you may need a few tests (urine analysis to check if the kidney is throwing out proteins in the urine, an indication of poor kidney function), blood studies (serum creatinine reflects the filtering ability of the kidneys. In addition to electrolytes like sodium potassium etc.), and definitely get your blood pressure measured (if the kidneys have a weak function, blood pressure goes up). A CT scan may also be required.
