I've been doing some pelvic floor drop exercises which have cut the urethral pain by more than half in
just a week.
The pelvic floor drop exercises immediately helped correct my issues with frequent voiding and urinary hesitation/intermittent flow.
Turns out, my hip bones are twisted, and so my pelvic floor muscles, which span my hip bones, are being stretched (as is my bladder, prostate, urethra, etc. - hence the pain).
