Q - Something else very intense happened a week after I saw you. My lower back, sacroiliac area just went right out. There were precipitating factors but I usually have thoracic problems not lumbar. I have had amazing practitioners and have been quickly healing – but it is still quite extreme and I have no idea how long it could be before it is (all?) healed. I may write you with more details but just wanted to throw out that big picture. I actually think back stuff is about trust and when we are injured somewhat seriously we must surrender quite a bit and soften up.
It is often i find that sciatica is triggered by not feeling support by someone who is in your inner circle. Why at this time i cannot say.
