#1. I doubt you dislocated both of your hips. Even 1 hip. You'd likely be in surgery right now. It is incredibly difficult to dislocate a human hip... I know, I've disarticulated a couple. This is why it is so rare to hear about hip dislocations, but very common to hear about hip fractures. Maybe you did throw your back out, which is just a histrionic slang for a muscle strain.
#2. You can't get 550mg or 750mg hydrocodone... one pill would kill you. That is probably the amount of the Tylenol they put with it. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif If it says "hydrocodone/APAP", then the first (and much much smaller) number is the amount of hydrocodone, the second number is the amount of Tylenol. Hydrocodone is typically dispensed in 5, 7.5, and 10mg doses, whether under the brand names Lortab, Lorcet, or Vicodin, the generic hydrocodone. Depending on your lifestyle and/or metabolism, it doesn't surprise me that it isn't doing much for you. I took one once and didn't notice much of anything.
#3. Hope you don't live alone.
