Hi,
Based on what I can understand from your messages on the board.
You had acid reflux symptoms before;you said you have UPPER LEFT abdominal pain,if so ,by location ,the pain is more relate to the stomach than to the liver.
You did not mentioned the exact locations of the 3 liver tumors you had;but if they are on the left and upper side of the left lobe of the liver,the chance of causing pain on the upper left side is also a possibility.
Chest tightness (ie: shortness of breath)can also cause you discomfort too because of the lung infection.
Levaquin,is a board spectrum antibiotic used for pneumonia,cholangiitis to urinary tract infections and it is appropriate for lung infection. You will feel better after 3-4 days of treatment(ie: improvement on breathing and chest tightness) but make sure you finish the entire course of treatment of the antibiotic.
If you think there is no improvement after the antibiotic treatment and the pain still persist; A visit to the GP or GI specialist is recommended.
Again, I am not a doctor but a CCA patient like you .
God bless.
