lower back pain liver

I am concerned about dull pain on my right front area, where the liver is…?
Last night I started having this dull pain when I’d lower my arms while driving on my right side below my breast towards the end of my rib cage, I think in the liver area…Can anybody give me some answers to what might be going on? It’s nothing but dull, if I lift my arm upwards, it goes away, but when I lower it I feel it again, but not all the time.
Any abdominal pain lasting more than three days should be looked at. A couple simple tests should zero in on it quickly.pp
