Are gallbladder, spleen, liver or kidney problems hereditary?

I had a u/s of my liver, gallbladder, spleen, and kidneys done the other day. They said the Dr wont get my test results back for a wk. And it is making me anxious. I am worried that my gallbladder is whats been causing dull pains. I have also been told that from blood work my liver is "slightly" inflamed, thus the reason for the scans. Could anything possibly go wrong while I am waiting? What signs should I look for? I am scared of severe pain and/or surgury. I have never had surgury or any health issues before.

The pain seems to have gotten a bit worse, since they did the u/s...I was thinkin it was just because of how they had to dig to get clear pics, but its now two days later and I am still what seems to be a bit sore. What do you think?

P.s. I have acid reflux and sinusitis(allergy)..could any of these things be what is causing an issue or the inflammation? For instance swallowing mucus when my allergies act up.
