If the doctor says plastic surgery 500, electromagnetic lights and the like don't believe 500, just do a simple phimosis operation. Everything else is a waste of money. If you go to a good hospital, 1300 can be done. After the operation, you can change the gauze yourself, wash the wound with iodophor, and take anti-inflammatory drugs orally to prevent the wound from breaking, for example, if the wound breaks too badly, it will be sutured again.
