@lgumerman. I have ongoing and chronic pain in my back and hips from osteoarthritis. It can be just awful so I know how terrible it is to live with this.

I can understand the reluctance of the psychiatric nurse practitioner in prescribing lorazepam since this is a controlled substance with known addiction potential. Are you also prescribed lorazepam in suppository form and oral form? Maybe taking lorazepam orally as well as in a suppository is too high a dose? Is that what the nurse practitioner said? I wasn't sure from what you posted.

I don't understand, though, what the problem is with prescribing pregabalin. That medication (brand name is Lyrica) is used to treat epilepsy but it also approved for muscle pain and stiffness in fibromyalgia.
I don't believe pregabalin has addictive potential from what I've read.

Psychiatry appointments can be difficult to get and schedule depending on where you live. You might find it easier to get in with and to talk to a physician who specializes in pain to get an idea of what alternatives might be available. Chronic pain can be such a challenge to treat and a physician who specializes in pain should be able to explain more about this and suggest alternatives to try.

What do you think your next step will be?
