About discogenic low back pain
Spinal discs are the cushions between the vertebrae. Each has a tough outer ring and a gel-like center. With age, repeated loading, or injury, small tears can form in the outer ring and the disc can lose height and water, which can irritate the nerve endings in the disc wall.
Discogenic pain tends to be felt in the middle of the low back and can spread into the buttocks. If disc material pushes out and presses on a nerve root, leg pain or sciatica may follow. Seek urgent care for new loss of bladder or bowel control, numbness in the groin, rapidly worsening leg weakness, or back pain with fever.
Common symptoms
- A deep, central ache in the low back
- Pain that is worse with sitting, bending forward, or lifting
- Pain that eases with walking or lying down
- Flares after coughing, sneezing, or a long drive
- Buttock or thigh pain, with leg symptoms if a nerve is involved
Common causes and risk factors
- Age-related disc wear, also called degenerative disc disease
- Tears in the outer ring of the disc from lifting or twisting
- Repetitive loading in heavy lifting jobs or sports
- Smoking, which reduces disc nutrition, and a family history of disc problems
How we diagnose it
Dr. Chen takes a careful history of what positions and activities provoke your pain, then performs a spine, hip, and nerve exam. MRI can show disc height loss, tears, or herniation, although disc changes are also common in people without pain, so findings are matched with your exam. When an injection is being considered, the imaging and exam together guide which disc level and approach make sense.
How Propel treats discogenic low back pain
Most disc-related back pain improves with a structured, progressive exercise program that restores tolerance for sitting, bending, and lifting. We focus on staying active, pacing load, sleep, and gradual strength gains rather than long periods of rest.
When pain persists despite good rehab, Dr. Chen may recommend an epidural steroid injection for pain that involves an irritated nerve. For carefully selected people with pain from the disc itself, intradiscal injections, which may include orthobiologics or ViaDisc, place supportive material directly into the disc. These options aim to ease pain and improve function; they do not rebuild a disc to its original condition, and evidence for them is still developing.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Questions about discogenic low back pain
- Does a bulging disc on my MRI mean it is the source of my pain?
- Not always. Disc bulges are common on MRI in people who have no back pain at all. Your history and exam need to match the imaging before a disc is treated as the cause.
- What is an intradiscal injection?
- An intradiscal injection places material directly into a painful disc using image guidance. Depending on the situation, that may be an orthobiologic such as platelet-rich plasma or a disc supplement such as ViaDisc. It is considered for selected people whose pain clearly comes from the disc and who have not improved with rehab.
- Is it safe to keep lifting weights with disc pain?
- Usually you can keep training with modified loads and movements while symptoms settle. A gradual return to lifting, guided by how your back responds, is often part of recovery rather than something to avoid for good.
