Hi
@MobiM
Once again I'm in catch-up mode and read sadly that you are going through a rough patch.
My heart goes out to you! Hugs and more hugs!
I am feeling the desperation in your post and am so glad you posted.
8 months and you HAVE made improvements but when you continue to have severe back and nerve pain,
the hip recovery can take second place. I feel at 8 months now you should take another look
on the rest of the pain sources.
It is that way for me. My actual hip replacement joint is coming along fairly well

if slower than I expected. But the rest of the pain girdle? Not so good. My second hip replacement is June 22 as it is clear I cannot move forward in recovery with that hip holding things up. This is such a journey, agree?
I do agree with Layla though about getting to the docs who can help you. Whatever it takes to do it.
Maybe a new pain specialist? Find one who is good! Did you say you had spine surgery? Maybe revisit that DR?
I know you like your current Dr, maybe he has new ideas?
Again I am going to share my moms story of laying in the back of the van to get anywhere. And if you need meds to make the ride -- so be it. Can you rent a small RV in your area? They have beds.
Ask your Dr about prolotherapy. Maybe you've already had it, but I'm throwing it out as consideration.
4 years ago I went though two courses of plasma rich protein ( PRP ) Prolotherapy. You can google it.
40+ injections into most of the tendon attachments from my waist down to my big toes and soles of feet.
Both legs. One month later - did it again. Chickened out for the final course.
It wasn't covered by insurance and it was expensive and make-you-throw- up painful. Many docs do not do it to this degree but as bad as it was, it helped!
I had had a different doc before who only did SI joint and it didnt help. He was not experienced in the technique.
It was a last resort for me because I was told to have spine surgery and both hips replaced.
The prolotherapy helped me. Gave me three years. Three functional and mostly pain free years.
I was able to finish my house build and move my family to our farm. It helped alleviate most of my nerve pain in my left foot and lessened my R sciatic nerve issues.
And if I would have behaved like a normal lady it would have probably solved more!
I feel I would be remiss to not suggest another look into medication that may help alleviate your nerve conditions. I know you have real intolerance to some and I agree that it must be thoughtfully considered,
however please discuss with your drs. Did you ever try a course of gabapentin?
It seems your back is against the wall on this pain/nerve issue and you must get to your docs to get resolution.
As far as agoraphobia goes; I have it. I am functional without medication now, but I will tell you, pain and the subsequent anxiety that can come from unrelenting pain can make my tolerance worse.
I look at medication and natural remedies as tools, to get me the help I need to function; to the point I don't need them any more.
Only wanting the best for you and praying you can find your way to some answers with your doctors.
