Female/ 35 years old/ mild to severe burning sensation while urinating since past couple of years. It reduces, if my daily water intake is more than 4-5 ltrs. Since past week, having pain in the pelvic area together with the burning sensation (while urinating). Have consulted couple of good doctors in the past. As per them, it's just infection. After taking antibiotics, it gets suppressed, but comes back again after week or so. Kindly advise.
