Bile duct blockage can lead to some of the symptoms you are describing.
If the ultrasound is negative, you may want to further investigate the biliary ducts to ensure there is no blockage. Stones or cancer can lead to blockage that may not be detected by ultrasound.
Specific tests to look at the biliary ducts would be an MRCP or ERCP, and I would consider these tests with your personal physician.
If negative, a liver biopsy can be considered for further evaluation.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
