Ultrasound & CT show liver cysts and hemangioma. Could these be the cause of discomfort under rt rib; digesting issues after polyp removal also.

Yes, it could be. Liver cysts and hemangiomas are for the most part, benign, but they can cause several symptoms - most commonly a vague pressure sensation in the right upper quadrant of the abdomen, sometimes radiating to the back. You should see a liver surgical specialist for further consultation.
