I agree with the others. Time to find a new GYN. I have Endo and PCOS, and did Lupron therapy b/c my gyn thought perhaps I had some endo growing in and around my spine and maybe that was causing some of my back pain. But here's the thing... I was on the Lupron for over a YEAR (!) before he said it was unlikely that endo was the back pain problem. And even then, he only said UNLIKELY. Not that it was definitely not the issue. According to him (and also to the gyn a friend of mine sees) the only way to definitively diagnose endo is to actually go in there and LOOK - with an exploratory lap or some other surgery. In my case, I ended up needing to have a hysterectomy for a variety of other reasons, but he left one ovary and I am now having some serious pain in that ovary so I am looking at maybe going back to get that one removed too. My doc said the Lupron would shrink the endo, but that takes time and it would not make it disappear altogether, so I wouldn't think they could completely rule out this problem after only a few months of Lupron treatment. I am, however, not a doctor. I'm just telling you what my doc told me and what my experience was.
I also think the others have given you excellent advice regarding the spinal concerns. That definitely should be looked at and ruled out or at least explored. In the early years of my back issues, my PM doc wanted me to see the gyn to do some specific testing to rule out the endo and pcos as potential pain triggers. Maybe you can find a PM and gyn who could work together to try and diagnose this problem for you.
One big caution I would give you is to NEVER go into any of your doctors' offices asking specifically for pain medication. I understand that you are in a great deal of pain. Trust me, I know how much these conditions can hurt! But unfortunately in the society we live in these days, asking for pain meds is classified as "drug seeking" behavior. That will immediately derail your quest for an answer here and will likely ensure that you will be unable to get any pain medication beyond tylenol or ibuprofen. The best thing to do (and I think maybe someone suggested this) is to keep a careful pain dairy. Journal your days - be specific about
how much pain you are having, what causes the pain to increase, what helps the pain settle down, what activities are you doing when you notice increased pain, are there times of day when it is worse/better, etc. If you search the forum, you will find several links to pain journals. Chutz (one of the moderators) has a link to a really good one. Using a journal to objectively tell your doc how the pain impacts your life can be a more effective way of communicating your need for medication. It gives you a chance to show that you are trying lots of things to mitigate the pain but it is still restricting your life a great deal.
Another good recommendation is to take someone with you to every one of your appointments. This person can advocate for you. Help to explain that the pain is really severely limiting your ability to live your life. They can ask the doctor for help on your behalf. Doctors often respond better to an advocate than to the patient themselves, plus your advocate can be more objective about
things since they are not in so much pain. They can also probably be more focused and remember more of the conversation. Most of us find it pretty hard to really concentrate when we are just trying to breathe without screaming b/c it hurts so much!
You can work with your advocate to create a list of points/questions/concerns ahead of time - including the pain journal. That way they will be able to be sure the doctor addresses all the issues you are struggling with.
Best of luck to you. And welcome to the forum. I am sorry for the pain that has brought you here, but I think you will find that the people here are remarkable and quite supportive.
