hi. noted history of elevated bilirubins, itchiness and bumps on different body parts. it is possible that you have an infection or obstruction (can be due to a gallstone disease or tumor lesions) somewhere along your hepaticopancreaticobiliary tree. this can cause the high bilirubin levels and itchiness (due to increase deposit of bile salts on your skin). bumps may be a secondary reaction due to scratching or manipulation when itching, otherwise, could be dermatologic in origin. it is best if consult with a doctor, preferably a gastroenterologist or a general surgeon, for complete physical examination and clinical evaluation. other diagnostics (such as ultrasound, ct-scan, liver function tests, blood counts, etc.) and management (medical and/or surgical if indications are found) will be directed accordingly. hope this helps. good day!! ~dr.kaye
