It could, everyone is different but since this is your first issue with prolonged use of opioids you shouldn't have too severe a time with it. The one major complaint of most during withdrawal are stomach/bowel issues. Get Imodium it will help a great deal.
Are you drinking enough? It's very easy to get dehy drated. Keep drinking. Sports drinks, juices, water, soups, popsicles will all help. Try some ibuprofen for the headache & other aches. Look @ the thomas recipe; it will help with the symptoms.
I had a really bad WD once and I didn't even realize I was addicted!
I have had a few WD experiences and most of them the 2nd day is the worst and it gets better on day three. It may linger around a bit. I would really get scared if you were laying down in bed not able to get up and sweating really bad with chills. I think that you got lucky (even tho the headache sounds bad). My guess is that you may start to feel better soon. My fingers are crossed for you because I now how uncomfortable it is!
