Anyone have a tight pelvic floor?

Anyone have a tight pelvic floor? I am suffering from a hypertonic pelvic floor due to a pelvic injury. As I am going through this, my PT and I are focusing on overall body tension. I cant help but think that my near 40 years of stuttering has compounded the problem of the tight pelvic floor. I think it is impeding my progress. Any one else have here experience similar where your stutter has effected your body in other ways?
