A constant low back ache, sometimes with sharp twinges down the leg, can make bending down or standing up straight feel like a negotiation. Many patients are offered a cortisone injection as the next step, but a corticosteroid shot manages symptoms temporarily and does not address the underlying joint, ligament, or disc irritation actually driving the pain.
At Precision Regenerative Medicine™, we treat the inflammatory process behind chronic low back pain directly, using your own concentrated platelets delivered under live image guidance. Targeted back pain relief in Phoenix, AZ is designed to reduce inflammation, reduce pain, and support spinal function, giving patients a non-surgical option before fusion or other invasive procedures become the only conversation left to have.
Patients searching for PRP back pain in Phoenix, AZ come to Precision Regenerative Medicine™ for a straightforward reason: every injection is planned and performed by a physician, not a technician, and every injection is placed under direct visualization rather than by feel.
I am Dr. Tammy J. Penhollow, DO, a dual board-certified physician in Anesthesiology and Pain Medicine, fellowship-trained at Stanford, and I practice exclusively in regenerative medicine. Precision Regenerative Medicine™ operates on a direct pay basis, which means your evaluation and treatment plan are built around your spine, not around what an insurance visit code allows time for.
The spine is not one structure. Facet joints, discs, ligaments, muscles, and the epidural space all interact as what’s known as the functional spinal unit, and back pain is rarely coming from just one of them in isolation. This is the foundation of the Tower of Power Spine® program at Precision Regenerative Medicine™: ultrasound guidance is used for the ligament and muscle components, while fluoroscopic, live X-ray, guidance is used for facet joints, the epidural space, the sacroiliac joints, and discs when indicated. Both modalities are typically used in the same visit, since treating one structure while ignoring the others rarely resolves the pain. We’ve written more about why this matters in why treating the spine one structure at a time is not a treatment plan.
I evaluate lumbar alignment, disc space narrowing, and imaging before determining which structures are actually involved and which imaging modality each one requires. Every injection is placed under live image guidance so the platelet concentrate reaches the intended structure directly, rather than surrounding muscle or fat.
Evaluation. I review lumbar range of motion, imaging (MRI when available), and prior treatment history, including any past corticosteroid injections, to identify which spinal structures are actually driving your pain.
Platelet preparation. A blood draw is processed to concentrate platelets to the level appropriate for the structures being treated.
Image-guided delivery. Concentrate is delivered directly into the ligament, muscle, facet joint, epidural space, sacroiliac joint, or disc involved, using ultrasound or fluoroscopy as appropriate for that structure.
Movement integration. Where appropriate, treatment is paired with Tower of Power Spine® core stabilization work, since an injection alone does not address the mechanical load the spine is carrying.
The visit itself is outpatient and typically runs about 90 minutes from blood draw to injection.

Most patients resume light daily activity, walking, sitting, routine tasks, within days of treatment. More demanding activity, such as heavy lifting or higher-impact exercise, is reintroduced gradually and often with some activity modification over the following weeks, as your spine’s response to treatment is reassessed.
A few things that support the process in the meantime:
Targeted PRP is most appropriate for adults with chronic low back pain from facet joint irritation, sacroiliac joint dysfunction, or ligament and disc-related pain who want a non-surgical option, including patients who have had a poor response to prior cortisone injections. PRP does not reverse structural changes like disc degeneration, and it is not a substitute for surgical evaluation when a surgical problem, such as significant nerve compression, is present. What it can do is reduce the inflammatory environment around the affected structures, easing pain and supporting function.
Whether back pain relief in Phoenix, AZ through PRP is the right next step depends on your imaging, which structures are involved, and what you’re trying to get back to, which is exactly what a physician evaluation is for.
Precision Regenerative Medicine™ is an interventional practice built around one physician doing the evaluating, the planning, and the procedure, every time. Led by Dr. Tammy J. Penhollow, DO, a dual board-certified physician in Anesthesiology and Pain Medicine with Stanford fellowship training, the practice combines advanced autologous biologic protocols with a deliberate stance against cortisone in regenerative care.
PRP uses concentrated platelets from your own blood to support the spine’s healing environment and reduce inflammation. Cortisone provides temporary symptom relief but can suppress the local healing response over repeated use, which is why we don’t use it in regenerative protocols. More on that here: why corticosteroid injections are not as benign as you’ve been told.
The full outpatient visit typically takes about 90 minutes, including the blood draw, platelet processing, and image-guided injection.
Yes. Spinal structures sit close to sensitive neural tissue and vary in depth and location, which is why the spine typically requires both ultrasound and fluoroscopic guidance in the same visit, matched to the structure being treated, rather than one imaging method for everything.
Most patients walk and manage light daily tasks right away. Heavier lifting and higher-impact activity are reintroduced gradually over the following weeks based on how the spine responds.
Corticosteroids can suppress platelet function and work against the local healing response PRP is designed to stimulate, which is why the two are not combined in our regenerative protocols.
If cortisone shots have started to feel like a temporary fix for back pain that keeps coming back, the next step isn’t another injection of the same kind. Schedule an evaluation with Precision Regenerative Medicine™ to find out whether targeted, image-guided PRP is the right fit for your spine.
If you are considering your options for chronic joint or spine pain, tendon or ligament injury, or non-surgical care in the Phoenix and Scottsdale area, I welcome the opportunity to evaluate your clinical picture and, if you are a candidate, determine which approach fits your presentation.
