Hi, I'm 18 Years Old. 2 Weeks Ago I Had

Hi, I'm 18 years old. 2 weeks ago i had a circumcision due to phimosis. Not sure but it was a high and tight circumcision. However, the swelling in my frenulum still exists, which according to the doctor should have been gone. My glans are hyper-sensitive to touch and i feel a stinging sensation everytime my boxers touch my glans. The stitches haven't come off yet and i dress the wound everyday with gauze bandage and apply Soframycin (prescribed by the doctor) twice daily. Currently, I'm not taking any medication as i finished the course. How long will it take for the swelling to reduce? And what should i do about my sensitive glans? And also after the stitches come off, will it leave any scars?

Thank You!
