<s>[INST] I was told I have lesions on my liver.  This was detected in 2011 while have a cat scan.  I have been experiencing back pain on my right side between my waist and ribs.  I also have fullness, belching pretty much all of the time and experience a hard time digesting my food,  Should I be concerned?
