What causes frequent urination and burning sensation while urination?

Hello,

Welcome to icliniq.com.

Thank you for your query. I understand your concern. Burning urination is caused by urethritis (inflammation of the urethra) that can occur due to urinary tract infections, and sexually transmitted infections. Bacterial infections can cause discharge. Urinary tract infections are rare in males, and they are often found secondary to obstruction due to stones. The treatment depends on the cause. I suggest you to get urine analysis and culture, STD (sexually transmitted disease) screening (only if you had any recent sexual contact), and ultrasound of kidney, ureter, and urinary bladder.

I hope this has helped you. Thank you.
