hi,
please look up http://www.drugs.com/cdi/percocet.html
Are you taking the medication with plenty of water and/or food? This medication can be harsh on the stomach and can cause gastric upset. I would hold off on taking them and see what happens. If the stomach issue doesn't resolve, I would definitely consult your physician.
well i messed my liver up from pain killers, and where your pain is is where mine still is, i havent taken pain killers in over a year now, except for the two days in march when i had my baby, and just fromthat little bit of percocets killed my liver. but also i had my gul bladder taken out a couple years ago, it had stones and caused the same pains so all you can do is get an ultrasound to see.
