What Causes Severe Pain In Upper Right Abdomen And Shoulder?

Question : Male 49 years old, 6.3 tall 250 lb. I have had a sharp pain in my upper abdomen on the right side with a corresponding pain on the back. I have had it for at least 3 weeks. Seemed to get worse lately. Swollen abdomen on the right side checked by two doctors but they didn't seem concerned. Corresponding shoulder pain ( I have rotater calf issues ). Initially a pulmonary embolism was suspected. I did a CAT scan to the lungs and all was negative. Did blood work ( included ) have ALT 74 ( 13-61 normal range ) AST 43 ( 15-37 normal range ). I feel tired. Oxygen level around 96. Moderate drinker ( 2 beers per week or less ). No other symptoms or relevant medical history. Did Hepatitis panel ( Waiting for results ). I have a cardiologist appointment scheduled for Monday. I am mostly concerned about liver cancer. My paternal-uncle had it when he was 55 years old but he was an alcoholic. I had to push to convince the doctor to do an ultrasound to the liver and will have to wait 3 weeks because he doesn't see it being an urgent type of testing. What could be going on with me? My doctor has no clue. He even told me to try to do some massages.
