Thanks for posting on HCM,
If all the above possibilities are ruled out then the other likely possibilities are overactive bladder
(urge incontinence), neurogenic bladder
( is a problem in which a person lacks bladder control due to a brain, spinal cord, or nerve condition), urinary tract infection
(all possible germs need to be cultured and identified after urine sampling) etc. Also get your prostate rechecked and screen for diabetes (fasting blood sugar).
You will need to revisit a urologist
who can do a proper evaluation and maybe offer a treatment if needed.
Hope this helps
