Back & spine

Back pain that has outlasted rest and therapy.

Lower back pain is not one condition. It is a symptom with roughly half a dozen common causes, and telling them apart is what decides whether treatment works.

Where lower back pain actually comes from

Most persistent lower back pain traces to one of a handful of structures: the facet joints at the back of the spine, a disc, the sacroiliac joint where the spine meets the pelvis, a compressed nerve root, or the muscles and ligaments around all of it. They produce overlapping symptoms, which is why "lower back pain" on an MRI report rarely settles anything on its own.

Imaging finds abnormalities in plenty of people who feel nothing at all. A bulging disc on a scan is not proof it is the source of your pain. So the work is to connect what the images show to what your examination and your history show — and, where two explanations remain plausible, to test them.

What we see

The problems behind most back pain

  • Facet joint arthritis — pain worse on standing, leaning back or turning
  • Disc herniation or degeneration pressing on a nerve root
  • Sacroiliac joint dysfunction — pain low and to one side, often mistaken for hip pain
  • Spinal stenosis — worse walking, better leaning forward on a cart
  • Spondylolisthesis, where one vertebra has slipped on the one below
  • Pain that persists or returns after spine surgery
  • Muscular and myofascial pain layered on top of any of the above

How it works

How we work out which one it is

  1. 01

    Examination that reproduces it

    Specific movements load specific structures. Which ones reproduce your pain narrows the list before any imaging is opened.

  2. 02

    Your imaging, read with you

    We look at your MRI or X-ray together and separate the findings that explain your symptoms from the incidental ones that do not.

  3. 03

    A diagnostic block, where needed

    Numbing a single joint or nerve under live X-ray answers the question directly. If the pain goes while the anaesthetic is working, we have found the source.

  4. 04

    Treat what we confirmed

    Injection, radiofrequency ablation, regenerative therapy or stimulation — chosen for the structure we identified, not for the region.

Over too many years I have seen too pain management guys. This one is different. First, he caught something on an MRI that only one other health professional had caught, including those reading the MRI, a cyst at the base of my spine pushing again the nerve. Second, his (their) treatment of it was first class. He took his time, was gentle. Concerned about my pain level throughout the process. Talked. Was funny, or at least amused by my jokes, a nervous habit and caring. Great experience!

My first visit with the "Ponte Vedra Spine & Pain Center" was "exceptional". The staff were very friendly & welcoming as well as professional. My meeting with Dr Loch was equally "exceptional." He carefully reviewed the MRIs & and evaluations of previous physicians, listened attentively while I reported the origins of my back problem through my current condition. He then fully explained the available procedures to treat my back pain & was very frank about how effective each procedure could be in alleviating my pain. Our visit concluded with a thorough plan to address my condition until our next meeting; Dr Loch prescribed medication to manage my pain, and set up a follow up appointment. I could not be more impressed with the Spine & Pain Center and happier with my decision to seek treatment with Dr. Loch & staff. J. B. Egan CAPT. USCR Ret.

The Team at PV Spine and Pain have been great. From initial reach out through completion of procedure and communication has been top notch. Dr. Loch took time to discuss my needs, answered my questions and is unquestionably is an expert in his field. It is a friendly environment with the staff that clearly is concerned with the patient’s well-being.

Questions we get asked

I have had an MRI and was told it looks normal. Can you still help?
Frequently, yes. MRI is good at showing structure and poor at showing which structure hurts. Facet joint and sacroiliac joint pain often produce an unremarkable MRI. Examination and diagnostic blocks are how those are identified.
Do I have to try physical therapy first?
Physical therapy is genuinely useful and often part of the plan. But months of therapy aimed at the wrong structure is a common reason people arrive here still in pain. Working out the source first makes the therapy more likely to help.
Will I need surgery?
Most people we see do not. The purpose of this practice is the ground between doing nothing and having an operation. Where surgery is genuinely the right answer, we will say so.
How long does relief from an injection last?
It varies with the diagnosis and the procedure. A diagnostic block lasts hours by design. A therapeutic steroid injection may give weeks to months. Radiofrequency ablation commonly gives longer, and can be repeated. We will give you a realistic range for your specific plan.
