[|Human|] Hello, I noticed a large dark purple bruise on my boyfriend s lower right abdomen. He has not been hit or otherwise injured, and there is only slight pain to the touch. His gallbladder was removed two months ago, if that is any help. I am worried because the bruise came out of nowhere and seems to be getting bigger.
[|AI|]  Hi. Thanks for your query. Read the history about your boyfriend and understood it. There is a history of gall bladder removal 2 months back. And now a bruise on the same - right side of the abdominal wall for no apparent reason. The possible cause can be reactivation of an infection in the abdominal wall post-surgery. Get an ultrasonography of the abdominal wall, X-ray to see if there is any Gas shadow. This indicates infection. Consult a General Surgeon and start on the treatment of antibiotics. If this does not settle with medicines, may need a Chat Doctor.
