Bulging Disc: How It Heals, How to Treat It, and Stem Cell Injections

Can a bulging disc heal, and do stem cell injections fix it? A bulging disc is a broad, usually age-related outward spread of a spinal disc, and it often causes no pain at all: imaging studies find bulges in 30% of pain-free 20-year-olds and 84% of pain-free 80-year-olds (Brinjikji et al., 2015). The bulge itself rarely shrinks, but the pain it is blamed for often settles with time, activity and physical therapy. Stem cell injections for disc problems are being studied, the evidence is still early, and they are not FDA-approved.

Bulging disc vs herniated disc

Each disc has a tough outer ring and a softer center. With age the discs lose water, flatten and become more likely to bulge or tear (AAOS OrthoInfo). The two terms describe different things on an MRI:

	Bulging disc	Herniated disc
What it looks like on MRI	The disc edge extends broadly and fairly evenly past the vertebrae, like a hamburger wider than its bun	A localized piece of disc material pushes out through a weak spot in the outer ring
Typical cause	Gradual wear with age	Wear plus a tear; sometimes lifting or a fall
Pressure on a nerve	Less common; often an incidental finding	More common; can cause sciatica
Shrinks on follow-up imaging	13% in a systematic review	41% to 96%, depending on type

If your report says herniation, protrusion or extrusion rather than bulge, our guide to stem cell therapy for a herniated disc is the better fit.

Can a bulging disc go away on its own?

Rarely on the scan, often in how you feel. A systematic review of patients treated without surgery found spontaneous regression in 96% of sequestered discs, 70% of extrusions, 41% of protrusions and only 13% of bulges (Chiu et al., 2015). Bulges are the least likely to change because they are part of the disc’s overall shape, not a fragment the body can reabsorb.

That does not mean you are stuck with the pain. In a review of 3,110 people with no back pain at all, disc bulges were common at every age and rose steadily with it, and the authors concluded that many of these findings are part of normal aging and must be read in the context of symptoms (Brinjikji et al., 2015). A bulge in the lumbar region on your MRI may or may not be the source of your pain, which is why the examination matters as much as the image.

How to fix a bulged disc: treatment that works first

The same first-line approach that orthopedic surgeons recommend for disc pain applies here (AAOS OrthoInfo):

• Short rest, then movement. One to two days of rest at most, then a gradual return to normal activity.
• Physical therapy. Exercises that strengthen the back and abdominal muscles.
• Anti-inflammatory medication such as ibuprofen or naproxen, if safe for you.
• Epidural steroid injection for nerve pain that has not improved after several weeks of other care; relief is often short term.

These treatments relieve symptoms while the body settles; they do not reshape the disc. Peptides such as BPC-157 are promoted online for bulging discs, but the FDA states it has no, or only limited, safety information for the proposed routes of administration and notes risks related to immunogenicity and impurities (FDA). We do not use it.

When surgery is the better choice

Only a small percentage of people with lumbar disc problems need an operation, but some should not wait. See a spine surgeon promptly, or go to an emergency room, if you have:

• Loss of bladder or bowel control, or numbness in the groin: possible cauda equina syndrome, a medical emergency
• Progressive leg weakness or difficulty walking
• Severe leg pain that has not improved after a full course of nonsurgical care

Timing matters too. AAOS notes that patients who try nonsurgical treatment for too long may improve less after surgery, with studies suggesting outcomes are better when surgery happens before about nine months. If your disc and spine are also unstable or narrowed, our guide to alternatives to spinal fusion explains when fusion is and is not needed.

Where stem cell injections fit

Stem cell injections for a bulging disc are an option to evaluate, not a first step. The 2023 systematic review of human studies on stem cells for degenerative disc disease found results that are promising in animals but still poorly understood in people, with no evidence yet to support routine use (Soufi et al., 2023). Stem cell therapy for back pain is also not FDA-approved.

You may be a reasonable candidate if your pain has lasted months despite physical therapy, your MRI and examination point to the disc as the pain source, your spine is stable, and you have no progressive weakness. You are not a candidate in the first weeks of a new episode, with any of the warning signs above, or with active infection or cancer. Our back pain therapy page describes how we evaluate spine cases, and this guide to chronic back pain covers other causes.

Treatment is priced per cell dose, from about USD 2,362 for 10 million cells to USD 4,725 for 50 million, converted from Colombian pesos every Monday; flights and lodging are separate. Most patients stay five to seven days in Medellín and are followed remotely afterward.

Frequently asked questions

Can a bulging disc go away on its own?

The bulge itself rarely disappears: one systematic review found bulges shrank on follow-up imaging in 13% of cases. The pain, however, often improves with time and physical therapy, and many people with bulges have no pain at all.

Is a bulging disc the same as a herniated disc?

No. A bulge is a broad, even extension of the disc edge, usually from aging. A herniation is a localized piece of disc pushing through the outer ring, and it is more likely to press on a nerve.

Do stem cell injections work for bulging discs?

The evidence is early. A 2023 systematic review of human studies found the clinical results still poorly understood. They may be evaluated for chronic disc pain in a stable spine after physical therapy has failed, but they are not FDA-approved.

Does BPC-157 help a bulging disc?

It is not an approved treatment for disc pain, and the FDA says it has no, or only limited, safety information for the proposed routes of administration.

Should I worry about a bulging disc on my MRI?

Not necessarily. Bulges appear in about a third of pain-free 20-year-olds and most pain-free 80-year-olds. What matters is whether your symptoms and examination match the finding.
