Thanks for your question. It is painful to hear about your problem. Anyway, it is not normal to have such a lot of pain following a surgery. I hope you should have been given with enough medication to prevent any pain or discomfort. If there is pain in spite of the medications administered, it suggests some complication during surgery. Wound infection can be a possible cause. It is better to return to your surgeon at the earliest and explain your symptoms to him in detail. He will be the best in prescribing any extra medications.
Get well soon.
