Hi.
Thanks for your query.
Noted the history and understood your concerns.
Since you have had no sex for the last 6 months pregnancy is out of question.
The cause of sudden pain in lower abdomen, pressure,
frequent urination, bloating and dizziness can be due to the following reasons:
Severe
urinary tract infection.
Pelvic inflammatory disease that is PID.
Intestinal infection.
Ovarian cyst with twisting.
This can be diagnosed by the following ways:
X-ray of the abdomen in standing position.
Ultrasonography of the whole abdomen.
Tests of urine: Routine, microscopy, culture and sensitivity.
Tests of stool and blood.
Clinical evaluation by a Gynecologist and a
General surgeon to correlate the reports and get a proper diagnosis so that a proper management can be done.
Go to the ER so that the things can be done urgently.
