Possible complications after vaginal tightening include infection, hematoma, wound dehiscence and adverse reaction from anesthesia. 1. Infection: If the procedure is not completely sterile, it may cause infection, which in turn may lead to inflammation. 2. Hematoma: If there is bleeding from the vagina after the operation, accompanied by a feeling of falling, a feeling of holding in urine, and a lump can be touched by anal palpation, it can be suspected to be hematoma, and generally speaking, if hematoma appears, it is necessary to go to the hospital for treatment in time. 3. Wound dehiscence: constipation or strenuous exercise too early after the operation may lead to wound dehiscence and bleeding, at this time you need to re-suture the wound and carry out anti-infection treatment. 4. Adverse reactions from anesthesia: If the dose of anesthesia used during the operation is too large, some adverse reactions may occur after the operation. It is recommended to go to a regular hospital for surgery, take some anti-infection drugs under the guidance of the doctor after vaginal tightening surgery, and avoid strenuous activities, which is conducive to wound recovery.
