I have suffering from piercing pain in my pelvic area during nights for about 8 months n feel as though my bladder is full at tht time, feel like passsing urine, but wen I pass urine it is just little, I had an usg abdomino pelvic scan and it was normal, recently I consulted a gyencologist who examined n said I have cervical erosion, is this pain only due to cervical erosion or Is it the begining of pelvic or cervical cancer? Please help
