Hello Ma'am. Very Good evening. As per your history given by you about frequent Pain in lower abdomen,  then you should do Ultrasound Whole abdomen Instead of Ultrasound lower abdomen. When the reports are ready,  kindly come to practo chat, I will tell you what to do further. But Ultrasound Whole abdomen is utmost necessary. In case of Pain,  meanwhile you can have Tab.  Meftal Spas as required. Good luck. Bye.
