Sounds like you need someone to have another look at his pain meds. My Alex was on 3 kinds during that last week and then for another 2 weeks. He had long acting oxycodone (Oxycontin), short acting oxycondone(Endone) and Fentanyl pathces. Still hurt like blazes but not so much that he had pain and chills.

Please talk to your doctors, this is too much pain for him.
