"after permanent sci (spinal cord injury), i&#039;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&#039;t worry about addiction, i&#039;ve got this the rest of my life, but every doctor i&#039;ve talked to warns of building a tolerance; better learn to live with a little more pain now rather than more pain later."
