Hello and welcome to Healthcare Magic. Thanks for your query.
The possible causes for discomfort / tenderness and swelling in the right side of the abdomen are:
- an enlarged liver
- soft tissue
swellings like lipoma
- sometimes acid peptic disease
or intestinal infections can present with abdominal discomfort / tenderness and a bloated or distended sensation (but not a definitive swelling).
You will need an abdominal examination to clearly ascertain the cause of your symptoms. I would advise you to see a doctor for a proper physicl examination and further management.
Wish you all the best.
Dr. Jonas Sundarakumar
