It really doesn't matter what treatment you've gone through, pain has to be managed as it's the enemy of healing. Pain will put your body in distress disrupting and slowing the healing process.

Now I understand that you are Canadian and they may do things different up there however if you are in a 9/10 range (roughly gauged as childbirth) then that's beyond an issue. I've always been told that pain is to be managed to a 4/10, that's low moderate pain so it's way past time to stop messing with the lightweight pain meds and dramamine and start hitting the juice ie hydrocodone and above.

Normally your dr will start you out with a 5/500 hydro however they have 7.5/500 and 10/650 (mg hydro/mg tylenol) and if those aren't cutting it then move up the scale to oxy. I'm a firm believer of more than adequate pain management so go with the big gun and jump to oxycodone, I'm sure it won't be an issue as you've got an opiate tolerance started due to the codeine. Whichever road you take, take it soon, you shouldn't have to be in pain.
