I do!! The injections didn't work for me. I had stenosis from L-1 through S-1. I am recovering from my 2nd surgery and have been in therapy for 1 1/2 years and I mostly don't have pain. I have to pace myself, exercise, meditate, and take Aleve twice a day at this point. Anyway, back pain can trigger PTSD, and PTSD can trigger back pain. I saw a pain psychologist who helped me a lot.
I was also a case manager at the hospital, which entails reading charts. In over 50% of back pain patients ( my estimate, not a proven study) people also had PTSD, or check the box that asked if they has suffered abuse.
There was also a study done on Adverse Childhood Effects. You can google it, it shows a direct correlation between trauma and illness later in life.
Even if it is triggered by emotions, you should probably have an MRI, since it is probably physical too. I was told there was NOTHING wrong with my back, and 2 years and 2 surgeries later I'm told my back is so fragile that I can't work. Boo.
