Hello doctors I am having a burning sensation only at early morning. Urine is yellowish and after i urinate it burns. Once i drink water the urine will be alright and i dont feel any burning sensation. I visited urologist and undergone ultrasound kub , uroflowmetry urine analysis and some blood tests. Everything is normal but usg report says cystitis with 15mm bladder thickness. I am worried if it is a bladder cancer . Doctor gave some medications for 5 days for uti infection. Kindly suggest if it is related to bladder cancer? I never smoked in my life and i take nin veg monthly once
