Is there a good treatment for 10/10 lower back pain?

Yes: The first and foremost one needs to know is why the pain is rated 10/10 which means almost a mortal pain. Very few conditions can cause such scenario. A pain specialist should be able to sort through the cause and come up with a multidisciplinary plan to alleviate the pain. These include but are not limited to minimally invasive procedures, surgery, medications, etc.

Usually: The success of any level of low back pain is very dependent upon the cause. Of course many other factors play a role in pain production and perception, but you must know the cause before anyone could delcare or propose a potentially successful treatment. You need to be evaluated by either an orthopedic spinal surgeon, or an interventional pain doctor for your answer.

10/10 back pain: This rating is meaningless without a full evaluation by an md be it a specialist or your pmd. Treatments are not provided based on a patients numeric rating. This is because what is a 10/10 to you maybe a 6/10 or a 4/10 to someone else. In acute pain the rating is quite good, in chronic pain it is very inacurate.
