Hi Bars,
Knowing where you are and who you would be dealing with, it's very likely they wouldn't have even looked at the liver to see if that could be an issue, and they surely didn't tell you what you should be doing next, did they? Are you
sure that you don't have pneumonia? Have you ever had bronchitis or pneumonia before so that you know what it 'feels' like?
If you are sure that's it's not bronchitis or pneumonia, then it's possible it's your liver, as Borderlyme has said. I like using this interactive thingy on this site to help me determine what might be hurting inside of me:
www.healthline.com/human-body-maps/small-intestine#4/1 I know that I can get pain and pressure in my liver when it's struggling. Asa matter of fact, I'm in the middle of a liver cleanse that my doc has me doing because I've been feeling that pressure and it's just 'that' time of the year.
Do you have any doc that you can trust? If so, I would suggest that you make an appt to at least have some blood work done to check your liver.
