Bloomers: Try to find a PT or a doctor who knows about core muscles, not the ones that they talk about when exercising, or the ones on infomercials, but the set of muscles three layers deep inside of your pelvis. I am on an exercise regiment where I exercise these through out the day. At first it seemed weird and annoying, but it really works. I could not sit for more than thiry minutes.
They tested it by having me *set my core* and then stand on one leg. I was all over the place and could not balance. This was because I had let my core muscles go after an injury. But, try it again after setting your core muscles and you can stand on one leg all day long. That is the test.
I do this weird thing where I lay down, imagine, but not move an arch across the lower back. Then, I imagine an arch inside of my back, down the middle of the pelvic region. Without tightening up the abs or obliques, I have to do Kegals. That sets your core. It sounds easy, but it took me a couple of weeks to master this and now I do it all of the time.
For three years, my DO told me to work on my abs/core. But, he was talking about the abs/obliques as a core. That did not help my inner muscles, which are actually your core muscles. You can't even feel them on the outside. They are three layers deep.
To figure it out, you, as a female, try to stop urinating half way through. Only try this once. If you can do it, your core is not really bad. If you can't, then your core needs work.
You might find that with working your core, the pain absolves itself. It is working for me
