Sharp stabbing pain upper right abdomen with Swollen,hard stomach?

43 year old female with sharp stabbing pain upper right abdomen to the center with no relief.Swollen,hard stomach. Started Monday evening. Hurts to breath & move much. I’ve had my gallbladder & appendix out 20 years ago along with a hysterectomy due to endometriosis. This came on out of no where, also I do not drink & have never done drugs( always a question docs ask when you go to doc). I just don’t want to go to the ER if it will go away. Any suggestions on what’s going on?
