Intermittent pain under your umbilicus
radiating to the bladder region is your complaint.
Do you find the pain increasing when the bladder is full..and the pain increasing during voiding?Pain associated with voiding can be caused by a patent urachus or the pull exerted on the median umbilical ligament.If there is also an umbilical discharge-it supports the condition.
Is there a swelling on and off at the umbilicus?cyst/hernia
to be ruled out.
it is advisable for you to get a check from the general surgeon
in order to rule out the aforesaid conditions ...
all the best
