Hello, I had a hysteroscopy on Wednesday and had a polyp removed and a sample of a thickening womb lining taken. I have some light bleeding, bright red but not concerning. Last night, I suddenly developed a pain in my lower left abdomen, pulsing in sensation.I have experienced this during the night. I am not in agony by any means but find this new pain very disconcerting. I have not needed any pain killers after the procedure at all. I am 52, a non smoker and in general good health.
