Hi.
Thanks for your query.
Noted the history and understood your concerns.
Pain on left side of abdomen, discomfort on left side of abdomen back and pelvis, appearance of a lump and feeling of bursting followed by per-vaginal bleeding can be due to the following reasons:
Bursting of anything other that the
hydrosalpinx that is inflammation with accumulation of pus in the
Fallopian tube alone can cause per-vaginal bleeding too.
Other cause of pain as you have mentioned can be due to colitis, left
ovarian cyst torsion and left ureteric stone.
This can be diagnosed y the following ways:
Clinical examination by a Gynecologist and
General Surgeon can help for the clinical diagnosis.
To be confirmed by the following investigations:
Ultrasonography of abdomen.X-ray of the abdomen in standing position.
Tests of blood, stool and urine can help further.
All things together can help to have a proper diagnosis a thus a plan of proper management.
