I hope by now you have a proper diagnosis. If not please know I am NOT a doctor but have been a sufferer of abdominal and pelvic adhesions for over 20 years. If you have pain that "doesn't show up on any test" but you know it is there consider finding a doctor most likely GYN that is very familiar with adhesions and seek help. Good luck to you.
HI,
The pains in the hip and buttocks can be due to osteoporosis that can affect menopausal women. Taking adequate amounts of calcium and vitamin D will help. For the pains in the vagina and bladder region and the feeling of something falling out, you should check out with your gynaecologist. Infection, senile vaginitis and prolapse of the vault of the vagina need to be excluded.
