Just to point out, it would likely be OxyContin (which is long-acting) along with percocet or oxycodone or some other immediate release narcotic.
I feel for you. I had joint replacement in my thumb, which failed five years ago. I wound up with complications and also wound up overmedicated through trying to control my pain. (I also have other pain issues; fibromyalgia, RSD, nerve pain, a herniated disk in my back and very bad arthritis in my hips and one knee and back.)
First, to keep YOU safe, only one doctor should be prescribing the Xanax and pain meds. Did you sign a pain contract? If so (and even if you didn't,) you need to follow your doctor's directions to the letter. Running out of medications can cause you to get dropped immediately, no second chances. Same with when you took the morphine. Even though it was previously prescribed, they could have dropped you.
I don't know anything about the Butrans patch for pain. I was on the Fentanyl patch and I had trouble with it sticking, especially in the summer and then as I went into menopause.
I've weaned myself off my meds for a number of reasons. Insurance companies and the DEA are making and going too continue to make it difficult for CP patients to be treated with narcotics.
You are clearly either under medicated and/or are on the wrong meds. Is there another pain clinic you can call and check out?
Your second issue is finding a surgeon who will do your hip replacements. When I went for the joint in my thumb, I was stunned. For years I had terrible pain but the ortho I was seeing kept giving me cortisone shots. I finally went for a second opinion who told me there was nothing left of the joint and the bones were all broken. That's when I went to hand surgeon who told me he never saw anything like it in someone my age.
Unfortunately, my implant failed (in just about everyone.) Since then I've had 9 further surgeries and countless procedures and medications.
You need two things: a surgeon. Start calling around. Check with any teaching hospitals that may have some names for you. Also, ask friends, relatives, etc., especially if they have any connection to the medical field.
Then you need a doctor or pain management clinic that you can develop an open, honest relationship with. They should be the ones prescribing narcotics and/or anxiety meds, sleep meds, etc. Leave the GP for your regular medical care. Your relationship with the pain clinic should be such that if your meds aren't covering your pain, you call them and they figure out what to do.
Also, by taking more percocet than prescribed you are at risk of taking too much acetaminophen as percocet contains Tylenol. If you then take other things with acetaminophen, you can easily go over the daily recommended safe dose.
I hope you can find some doctors that can give you the treatment you need. Staying with these ones will bring you more misery I believe.
From what I see and think is that you are terribly undermedicated. Simple as that. if you were on Oxycodone, with percocet for your breakthru moments, I think you'd be amazed at the difference in pain levels. it scares me to know you are already at a pain clinic. One would think that they would know what is indicated to help you. I understand that some doctors are weary of prescribing opiates, but come on now! Good Luck.
I can't really help with med advice, but i too have groin pain and the NP at my pain clinic said that yes it very well could be from my back, i believe she said it could be because of the problems I'm having at l4, the nerves in L4 reach around to the groin area. I hope that helps and best of luck to you.
