Hello dear Understand your concern I think mechanical trauma by the jumbpo sharpie cause swollen and painful vagina. Rough activity injured the post vaginal wall, superficial venous plexus of cervix and vagina. Inflammation produce swollen vagina. Follow these advice: Avoid such kind of masturbation. If you want to use then use with the proper lubrication but do not push so much high inside the vagina. Take warm sitz bath with added betadin that increased the healing process. Take meftl spas. apply apple cidar vinegar. Wear pure cotton loose undergarment. Hope this will help you Contact HCM for further health query Best regards Dr. Sagar
