For last two years I am suffering from urinery tract infection once in a 2/3 months. Everytime I consult with doctor and take prescribed medication I get relief for a while. Four months back I sufferd the same. I consulted with doctor and had 'urine test' and 'sonography' which showed swollen in both kidneys, bladder infection and urine infection.i took prescribed medication for more than a month and got relief. Now I am suffering again for last 3 days and this time having mild pain and burning in kidneys also. Please tell me how much serious is this and guide me.
