Hello @dougs72 . Welcome to Connect. There is a condition called Lumbar Plexus Compression Syndrome and it can mimic a spine problem. There are several muscle groups that connect the spine and the pelvis, and if those get too tight, it pulls on the spine and pelvis, and can pull the pelvis out of alignment. I have had this happen and when my pelvis is off, I get low back pain on one side, and sometimes pain radiating from the groin, and sciatic pain. If the hip flexors get too tight, it can trigger this. I have worked with my PT who does myofascial release and the key to fixing that for me, is to loosen the muscles who are causing it. Here are a couple of links for information.

Neuropathy - "Myofascial Release Therapy (MFR) for treating compression and pain"

Myofascial release is specialized training and not all PTs know his technique. You can search for an MFR trained therapist at this link. http://mfrtherapists.com/

I do MFR a lot, and I continue to do it at home as I cannot see my therapist as much as I would like, but she will help if there is something I can't do myself. I am a spine surgery patient too and had cervical surgery. This is a lot of slow stretching of tissue and fascia to get it moving again and relieve the pain. It really can help, but it takes a lot of sessions as you work through the layers. You don't need a specific diagnosis to do this. Pain is enough to warrant PT sessions. Find the right therapist who has more training in fine tuning.
