Hydromorphone
"After permanent SCI (Spinal Cord Injury), I've had a lot of experience with pain. Hydromorphone 4 mg was prescribed for break-through pain and has worked pretty well. I agree, better learn to live with a level of 4 (out of 10). I don't worry about addiction, I've got this the rest of my life, but every doctor I've talked to warns of building a tolerance; better learn to live with a little more pain now rather than more pain later."
