Hello and welcome to Healthcare Magic.As mentioned above your problem started after you underwent a vaginal hysterectomy
.There is a possibility that during the operation some of the nerves of the urinary bladder
or the ureters may be affected. The question is whether the control is lost only during urination or otherwise also.
Pain while doing the pelvic floor
exercise is because the surgery is recent and wounds are fresh.You can take the help of homoeopathy as we have medicines which can help to reverse the damage caused by the surgery.Hope that your queries are solved
