Could be UTI. Urinary tract infection(uti) especially bladder infection(cystitis) is a common cause of burning on urination. It will also make you run to the bathroom more frequently than normal. If you have these symptoms, you need to go see your doctor and get a urinalysis done. Antibiotics may be prescribed by the doctor if he/sghe suspects uti.
