Hi, thanks for posting your concern in the HCM. My understanding is you may have itching if you have obstructive jaundice or conjugated hyperbilirubinemia. This is due to deposition of bile salt. However, any form of rash during jaundice should be evaluated as early as possible. They should be differentiated from purpura or telangiactasia. Furthermore, whenever an obstructive jaundice is suspected, any form of cholangitis should be evaluated for, because acute cholangitis is considered as an emergency. For the time being, you may apply calamine lotion over the rash for symptomatic relief. Please visit your doctor as early as possible. For any further query please write back. Regards, Dr. Kaushik
