Disc Disorders
When a worn, degenerated disc herniates, it can press on a nerve and cause radiating pain. At Desert Spine and Pain, Dr. David L. Greenwald, MD, FAANS, FACS, a dual board-certified spine surgeon and neurosurgeon, treats both the herniation and the underlying wear — least-invasive-first.

A degenerative disc herniation is a herniation that happens in a disc already weakened by age-related wear. The worn disc is more prone to tearing, and when it does, the escaping material can press on a nerve — causing sciatica or arm pain on top of chronic stiffness. At Desert Spine and Pain in Phoenix, a dual board-certified spine surgeon and neurosurgeon treats both problems with a single, least-invasive-first plan.

A degenerative disc herniation combines two problems: a disc worn down by degeneration, and a herniation where that weakened disc tears and pushes material onto a nerve. Because the disc is already thinned and brittle, it herniates more easily — often with less force than a healthy disc would need.
The result is usually chronic stiffness from the degeneration plus the sharp, radiating pain of nerve compression. Treating it well means addressing both the herniation and the worn disc behind it.
See a specialist when radiating arm or leg pain develops in the setting of known disc degeneration, or when chronic back pain suddenly becomes sharp and shooting. Early treatment relieves pain and protects the nerve.
Go to an emergency room or call us immediately if you develop progressive leg or arm weakness, numbness around the groin, loss of bladder or bowel control, or symptoms following a significant accident or fall.
We treat degenerative disc herniation least-invasive-first, relieving the nerve compression while managing the underlying wear.
Physical therapy through our on-site partner BackFit Health + Spine settles many degenerative herniations as inflammation resolves.
An epidural steroid injection reduces inflammation around the compressed nerve and relieves radiating pain.
When pain persists, a lumbar microdiscectomy or minimally invasive microdiscectomy removes the herniated fragment.
If the worn segment is unstable, a spinal fusion stabilizes it along with relieving the nerve — reserved for cases that truly require it.
Choosing the right degenerative disc herniation specialist in Phoenix matters. At Desert Spine and Pain, your care is led by Dr. David L. Greenwald, MD, FAANS, FACS — a physician who is both a board-certified spine surgeon and a neurosurgeon. That dual expertise is rare, and it means one expert can guide you across the full spectrum of care — from a simple injection to complex surgery — and recommend what is genuinely best for you, whether you need a degenerative disc herniation doctor for conservative care or a surgeon when surgery is truly the answer.
A rare dual credential — so the specialist who treats you can also perform surgery if it's ever needed.
Most patients get better without surgery. We only advance when your condition truly requires it.
No referral needed. We make it straightforward to see a top spine specialist, even out-of-network.
24/7 concierge response and close coordination with personal-injury attorneys.
Life Beyond the Pain

From your first visit, the goal is a clear diagnosis and a plan built around you — not a one-size-fits-all protocol.
We listen to your history, examine you, and review any prior imaging — no referral required.
If needed, we order or review MRI/X-ray imaging and may use diagnostic nerve testing or a diagnostic injection to confirm the exact source.
Dr. Greenwald explains your options in plain language and starts with the least invasive treatment likely to work.
We deliver your care — therapy, a procedure, or surgery at an affiliated accredited facility — and follow you closely until you're back to living.
Cost and coverage shouldn't stand between you and relief. Desert Spine and Pain welcomes out-of-network patients and will walk you through what your evaluation and treatment are likely to involve before anything is scheduled — so there are no surprises. We'll help you understand your benefits and options, whether you're using insurance, paying out-of-pocket, or being treated under a personal-injury claim.
If your pain started with a car accident, slip-and-fall, or work injury, we offer a dedicated pathway: prompt evaluation, thorough documentation and records for your case, and direct coordination with your personal-injury attorney. You focus on recovering; we handle the medical side.

Book a Consultation — (602) 566-9500How is this different from a regular herniated disc?
A degenerative disc herniation happens in a disc already weakened by age-related wear, so it combines chronic degeneration symptoms with the sharp, radiating pain of a herniation. Treatment addresses both.
Will I need surgery?
Usually not at first. Most degenerative herniations settle with conservative care and an epidural injection. A minimally invasive microdiscectomy is considered if pain persists or there's significant weakness.
Could I need a fusion?
Only if the worn segment is also unstable. In that case a fusion both relieves the nerve and stabilizes the spine — but it's reserved for cases that truly require it.
Do I need a referral, and are you out-of-network?
No referral is required, and we welcome out-of-network patients.
