I have had this pain for about 6 years, I suspect I have always had a tendency to tightness in my pelvic floor but a series of pelvic surgeries brought it to the fore. On palpation though vagina I have trigger points on the left side of pelvic floor which may be associated with' twist' in pelvic bones.It has not responded to injections of local anaesthetic and cortisone. I am considering having botox injection but concerned it will increase stress incontinence. It seems to be triggered by lying in the one place and sleeping soundly but could it be caused by involuntary clenching of pelvic muscles as some people clench their teeth when asleep? I nearly always wake with this pain but if I didn't have to sleep or could sleep in a chair I wouldn't have CPP!
