under ultrasonic guidance req.
I have carefully read your query and understand your concern.
This swelling in your case is unlikely to be a lipoma considering its site of origin.
Swellings in this area(right side of abdomen below rib cage
) are mostly likely to be of hepatic(liver)origin.
I advice you to have an Ultrasound
If the swelling found on the scan is of solid consistency(ruling out vascular swellings),then a Percutaneous biopsy under ultrasonic guidance is needed to determine its histology and to guide further treatment.
Liver swellings are known to cause dragging sensation like pain with localisation under the mid Epigastric region(below sternum
In case if you are currently on any oral contraceptive
medications ,I advice you to stop them ,since few swelling like Hepatic Adenomas(which are common in your age group) are known to increase their size and bleed under the influence of OCP's.
Consult your treating doctor with reference to above investigative protocol.
I Hope this info is helpful to you,at this moment of time to guide you further,
In case of further queries,post them to http://bit.ly/drsureshheijebu
