Try taking two of either said pills.
Also, this might be pushing it as far as meds go - by maybe try taking 2 Narco and 2 more 200mg ibuprofen pills. 800mg ibuprofen might just be a better way for pain management, that and with 15mg hydrocodone, you should feel quite a bit better.
Or instead of going to 15mg straight, try 1 and a half Narco, which would be about 11mg hydrocodone, and get you about 700mg ibuprofen if taking 2 more ibuprofen alone.
ibuprofen tends to be best for me when it comes to general soreness, whereas hydrocodone just makes me feel warm and takes my mind away from pain. Then again, I've never had it prescribed for any serious pains, just a nasty fever and got some Lortab Elixer (hydrocodone).
My dad is taking hydrocodone for some back problems, some issue with a swelled disk. So my genes seem to respond pretty well to the drug, thankfully. I couldn't imagine pain meds not working (OTC pain meds suck for me, I've used them so much in my life, shit doesn't work well. hell, 800mg ibuprofen doesn't work for me all that well because I use ibuprofen so much, especially recently with my back/neck seemingly out of alignment/just generally fucked up for some reason that I know not.
