Hydromorphone
"I've been taking this in tablet form for failed back surgery, and CRPS in both legs up to the thigh. It doesn't relieve all the pain, but it relieves enough to get me through my day of being a full time stay-at-home single dad. I think I got better relief from the oxycodone I was on before, but it would only last 2-3 hours, whereas the Dilaudid lasts a solid 4 hours, so I get a little bit more time with my little guy where my pain is under control. Wish I could take the ER version, but due to gastric bypass, no ER tablets work on me... Can't say it's given me my life back, because I was a wind turbine technician when I became disabled, but I get enough relief to be with my son instead of on the bed in relentless agonising pain."
