HI ABrown,
Four days have passed since you posted and I hope your flare is quieting down. I don't have any information to offer about dilaudid, but I did want to say that the at least now you can rule out the other med options that your doc tried and move forward with other choices. hannah's doc has a unique rhythm of administering meds..it makes sense to prescribe seasonally, or any other intermittant way, and this way the body doesn't build up a tolerance!
It's so hard to know if the pain is increasing, or if the med is simply no longer effective on the current level of pain. It would be an interesting question to ask the doc's..
I truly hope the week-end and the dilaudid brought you some relief..
Hope4thebest
