pain
"I have chronic back and neck pain from 2 car accidents, I was rear ended.  Had to have a 3 level cervical fusion with titanium plate 5 years ago. 
I was on Exalgo 8 mg, with Dilaudid or Norco for breakthrough pain.  Norco always worked better for breakthrough pain, but don't like being forced to take acetaminophen that's in Norco.  Just switched to 10 mg Zohydro 2x/day.  Side effects were headache, nausea  and a knot in my stomach.  Which lasted the first 1-2 hours.  My Md gave me Zofran for nausea which worked.  My pain control is great!  I am also sleeping much better.  I do take some Norco for breakthrough, but so much better! This is day 3, and side effects seem to be gone! Great medicine.  Need to get coupon working for me.  Thanks Zohydro!"
