I have pain on both sides of my ribs, radiating down my legs and behind my hips. The pain is sudden and severe, manifested by repeated farting, a feeling of heaviness in the lower abdomen. I went for a blood test and the doctor told me I had irritable bowel syndrome and gave me medicine, but the pain still didn't go away. The doctor did not recommend re-examination. Severe pain in the ribs spreading to the legs and hips, what is the disease?

I have hepatitis B and have been on antiretroviral therapy for almost 2 years. Recently, I have noticed that the skin on the backs of my hands and soles of my feet turns yellow and there is a slight pain in my right flank. I did the tests and they are all normal
