Hello, Frenulum tear is usually due to vigorous masturbation or partner sex or wearing uncomfortable pants or underwear. The penis is a dense bundle of nerves and receptors, so it’s normal for your torn frenulum to hurt more than you might expect. Oftentimes, any initial bleeding or intense pain will fade in a matter of hours. You may feel a dull, aching pain for a few days afterward as the injury heals. If the injury becomes infected, your symptoms may worsen and go on to include unusual penile discharge, foul odor, and fever. These symptoms could last for a week or more if the infection isn’t treated. An untreated infection can also spread to other parts of your penis and cause more widespread, severe pain. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr K. V. Anand, Psychologist
