A 59-yr-old male, a victim of an road traffic accident, sustained polytrauma, undergone multiple sessions of definitive and reconstructive surgeries and now waiting in the ward for another surgical session. One of his dehiscent wound is on continuous suction and causing a little pain. He can not sleep at night without introducing a Diclofenac suppository. He has to take about 400 suppositories within last 3 months! What is the explanation and remedies please?
