I am having a spinal injection tomorrow and the pain management doctor told me not to take any Motrin products for 24 hours before having the injection. I have been taking hydro codons as prescribed by an orthopod who is also treating me for sciatica and referred me to the pain mgmnt. doctor. Is it safe to take one hydro codone- /acetaminophen 5-325 tonight ? The injection, the first of three is scheduled for 1pm tomorrow. ???? Lois Holmes
