Hi, Welcome to Health care magic forum.
Anyhow what ever the reason, it is always nescesory to consult a gynecologist for diagnosis , to avoid any further complications.
You may need to have a MRI
for confirmation of the conditin.
Other reasons may be the urinary tract infection
, or stone in the ureter
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to hasten the recovery.
Wishing for a quick and complete recovery. Thank you.
