Should have been a coma after "hydration". You need a physical rehab specialist to show you how to use the TENS.
Both medicines do bupkis for back pain. Bupkis means nada, nothing. Anti-inflamatories, special exercises, hydration a TENS device, and as a last ditch, a laminectomy. Neither medication is "better for the pain". The best investment you could make is a physical rehab therapist who can show you several of a dozen exercises that will absolutely positively make your life much easier. It is impossible to understand these exercises by viewinmg them on the net or reading a book.
it all dope, which isn't always a bad thing as opiates are the best pain killers. Lorcet is hydrocodone and percocet is oxycodone which is stronger. both addictive!
