I did pelvic PT for endometriosis. It was external. And it helped.
I also did internal pelvic PT for frequency and painful intercourse. It didn’t help me but to be fair, no treatment has helped. I’m a lost cause here. Others do get better. I’m now wondering if I have endometriosis on my bladder because typical treatments work for others but not me.
I’d love to hear if it helps. And I’m really not a fan of these invasive treatments but you become used to it and you are kept covered up.
