Could Severe Constipation Be Due To Hydrocodone?

I have not eliminated in over a week. In the last few days, I ve had 2T of Benefiber, 2 capfuls of Miralax, exercise and lots of veggies and water. In the last 2 days, I ve had 4-5 enemas. Nothing has worked. I am also on Hydrocodone twice a day, which I understand is constipating. What should I do now?
