I have had this for years (Different name, as part of MCTD) and found relief at a manual PT, rocabado trained. It is piriformis/sciatica and working to lengthen and strengthen the muscles is incredible. Not a woowoo fix, but works well with meds. I do not like gabapentin. Dr Jo you tube is great and the Two Guys video after it also explains well. Give it a try! https://www.youtube.com/watch/iqQDmakOvN8
