Burning sensations experienced during or after urination are typical for cases of inflammation of the urethra (urethritis). A bladder infection (cystitis) manifests the same symptoms plus frequent urination and lower abdominal pain. Urethritis can be due to an infection, irritation, or allergy.Urinary tract infections (urethritis and cystitis) are more common in women than in men. To confirm urethritis, one must perform a microbiological examination of the urine and give a urethral sample. Usually antibiotics don’t have any effect if urethritis is caused by irritation or allergy, and would not be prescribed.
