Multiple abdominal issues: Should I get an earlier appointment?

Hello!

I recently did an upper abdominal USS which was prescribed by the surgeon I am currently seeing for gallstones. In addition to multple gallstones, the findings also included a 9.5cm x 6.1cm x 7.6cm (volume - 228cc) avascular, tender cystic mass in the left upper quadrant between the spleen and the left kidney.

I cannot lay down on my left side as it causes pain. Most of the food (if not all) that I consume results in nausea, sometimes severe. I also get a throbbing pain in the area semi-frequently. Sometimes, I also hear loud noises coming from my stomach after eating.

My diet consists of fruits, veggies, white meat, fish, whole wheat/whole grain bread, rice (maybe one every 2 to 3 weeks - not a rice lover), pasta (at least once a fortnight), fresh salads, peas, beans, nuts, eggs, very little cheese, milk, water. I am also currently on a no-salt, no-sugar diet.

Even though my surgeon wanted the abdominal ultrasound done, I received a call the day before my clinic appointment stating that my appointment had been changed to April 2022. Needless to say, he never looked at the results of the ultrasound. I just wanted to find out if this is something I should be concerned about to get immediate medical attention to or can I hold out until April next year?

Thank you.
