@red3 It's nice to see you here and I hope your surgical recovery is going well. I found a few links about myofacial release for female issues, and you would want a physical therapist who does pelvic floor work. You would want a female therapist. My physical therapist has talked about some of this, but I don't have experience with these issues. Some pelvis work which I have done is pressing on the tight muscles surrounding the pelvis and spine connection to level it if it is rotated out of shape or the sacrum externally. The iliac bones can be twisted or inflared which causes low back or sciatic pain. Pelvic floor work can be internal. Here are some links that describe this with MFR, and to the therapist, this is just another way to access the muscles. If you find a therapist you are interested in, call them and ask questions about how they treat these issues and what to expect. John Barnes developed the myofascial release techniques and is referenced in the first link.

Another MD specialist for incontinence is a Urogynecologist. There can be different reasons for incontinence that can be weakness in the pelvic floor or a physical issue in the mechanics or a spine or nerve problem. Some treatments done by the Urogynecologist include injecting a bulking agent to help the urethra be able to close tighter, pelvic floor therapy with electrical stimulation to strengthen the muscles, Botox injections internally in the wall of the bladder to decrease overactive contractions (usually done every 6 months), and UV internal treatments or hormone replacement which helps the pelvic floor maintain health and strength.
