OK, it sounds like your doing everything. Darvon doesn't work for me the best ER meds for me are temesic, stadol, fenatyl.
And if you are in so much pain but still have the use of extremities you can either re-do it or live with it(using meds)
Mine is not surgically correctable, now. Unless I lose feeling in my legs again - they won't do a third on on me.
They do however give me enough pills to keep me out of ER - they woudl rather I take 8 vicodin(or norco) than 10-20mg morphine(in ER). I get a ridiculous amount of hydro.
