Back pain from arthritis is common in older adults, and treatment options range from physical therapy and medication to injections and surgery

Back arthritis develops when cartilage in the spine wears down over time, causing pain, stiffness, and sometimes nerve problems. The pain may be constant or come and go, and it can affect your ability to walk, bend, or sit comfortably. Treatment depends on how severe your symptoms are and what your doctor finds during examination.

Most people start with non-surgical approaches: over-the-counter or prescription pain relievers, physical therapy, heat or ice, and activity changes. If those do not work well enough, your doctor may suggest injections into the spine or, less commonly, surgery. The goal is to reduce pain and help you stay active, not necessarily to cure the arthritis itself.

Key Takeaways

  • Back arthritis pain often improves with physical therapy, anti-inflammatory medications, and activity changes before you need injections or surgery.
  • Your primary care doctor or a rheumatologist can diagnose back arthritis with imaging tests and help you choose a treatment plan that fits your situation.
  • Steroid injections into the spine can reduce pain for weeks or months and are less invasive than surgery, though they are not permanent.
  • Medicare and most insurance plans cover physical therapy, medications, and injections for back arthritis, though you may have copays or deductibles.
  • Staying active, maintaining a healthy weight, and using proper posture reduce strain on your back and can slow arthritis progression.

How back arthritis develops and what causes pain

The spine is made up of bones called vertebrae, separated by discs that act as cushions. Between the vertebrae are small joints that allow your back to bend and twist. Over time, the cartilage in these joints can wear down — a process called osteoarthritis — or inflammation can develop, as in rheumatoid arthritis. When cartilage thins, bones may rub together, causing pain and stiffness.

Back arthritis pain often feels like a dull ache in the lower back, though it can occur anywhere along the spine. Some people feel sharp pain when they move in certain ways, or numbness and tingling if arthritis narrows the space where nerves pass through. Pain may be worse in the morning, after sitting for a long time, or when you bend backward. The pain can range from mild to severe enough to interfere with daily tasks.

Risk factors include age, previous back injuries, heavy lifting over many years, and family history of arthritis. Being overweight puts extra stress on the spine. Some people have no symptoms at all, even when imaging shows arthritis is present.

When to see a doctor and what tests to expect

See your primary care doctor if back pain lasts more than a few weeks, gets worse over time, or interferes with sleep, work, or daily activities. Also seek care if you have numbness or weakness in your legs, loss of bladder or bowel control, or unexplained weight loss — these can signal a more serious problem.

Your doctor will ask about when the pain started, what makes it better or worse, and how it affects your life. They will examine your back, test your strength and reflexes, and may ask you to bend or move in certain ways. If arthritis is suspected, your doctor may order X-rays or an MRI to see the spine and confirm the diagnosis. Blood tests are sometimes used to rule out rheumatoid arthritis or other conditions.

Your primary care doctor can manage mild to moderate back arthritis, or they may refer you to a rheumatologist (a specialist in arthritis) or a spine specialist if your case is complex or if you are considering surgery.

Non-surgical treatment: medication, therapy, and lifestyle changes

Most people with back arthritis start with non-surgical approaches. Over-the-counter pain relievers like acetaminophen or ibuprofen can reduce pain and inflammation. If those are not strong enough, your doctor may prescribe stronger pain medication or muscle relaxants to ease stiffness. Some people benefit from topical creams applied directly to the skin over the painful area.

Physical therapy is often recommended and can be very effective. A physical therapist teaches you exercises to strengthen the muscles that support your spine, improve flexibility, and reduce strain on arthritic joints. Sessions usually last 30 to 60 minutes, and you will be given exercises to do at home. Most insurance plans, including Medicare, cover physical therapy when prescribed by a doctor.

Heat therapy — using a heating pad or warm bath — can ease stiffness and muscle tension. Cold packs can reduce swelling and sharp pain. Activity changes matter too: avoid heavy lifting, use proper posture when sitting and standing, take frequent breaks if you sit for long periods, and stay active with walking or swimming, which are gentler on the spine than high-impact exercise. Maintaining a healthy weight reduces stress on your back.

Injections and when your doctor might recommend them

If medication and physical therapy do not control your pain well enough, your doctor may suggest a steroid injection into the space around the nerve roots in your spine (called an epidural steroid injection) or into the small joints of the spine itself (called a facet joint injection). These injections deliver anti-inflammatory medication directly to the painful area.

Injections are done in an outpatient clinic or surgery center, usually under light sedation. The doctor uses imaging to guide the needle to the right spot. The procedure takes 15 to 30 minutes, and you can usually go home the same day. Pain relief often begins within a few days and can last weeks or months. Some people get one injection; others have a series of two or three spaced weeks apart.

Injections are not permanent, and they do not stop arthritis from progressing. However, they can reduce pain enough to let you do physical therapy and stay active, which can slow decline. Most insurance plans cover injections when conservative treatment has not worked, though you may have a copay.

Surgery: what it involves and who might need it

Surgery is considered only when other treatments have not worked and pain is severe enough to significantly limit your life. Common procedures include removing bone spurs or thickened ligaments that pinch nerves (called decompression), or fusing two or more vertebrae together to stabilize the spine. Surgery is done by a spine surgeon in a hospital operating room.

Recovery from spine surgery takes weeks to months. You will have restrictions on bending, lifting, and activity while the spine heals. Physical therapy is part of recovery. Surgery carries risks, including infection, bleeding, and nerve damage, though serious complications are uncommon. Success rates vary depending on the type of surgery and your overall health.

Your doctor will discuss whether surgery is likely to help your specific problem and what the risks and benefits are for you. A second opinion from another spine surgeon is reasonable before deciding to have surgery.

Insurance coverage and costs

Medicare Part B covers doctor visits, imaging tests, physical therapy, and injections for back arthritis. You pay a copay for each visit and 20 percent of the cost of imaging and injections after you meet your deductible. Prescription medications are covered under Part D (prescription drug coverage), with copays that vary by plan.

Private insurance plans vary in what they cover. Most cover doctor visits, physical therapy, and medications. Some require prior approval from the insurance company before you have injections or imaging. Check your plan documents or call the customer service number on your insurance card to understand your coverage and out-of-pocket costs.

If cost is a barrier, ask your doctor about generic medications, which are much cheaper than brand-name drugs. Some pharmaceutical companies offer information programs for people who cannot afford medications. Physical therapy through a community center or senior center is sometimes lower-cost than a private clinic.

Frequently Asked Questions

Can back arthritis pain go away on its own?

Mild back pain sometimes improves with rest and activity changes. However, arthritis itself does not go away — the cartilage damage is permanent. With treatment, pain can be controlled well enough that it does not interfere with your life, even if the arthritis is still present on imaging.

Is it safe to exercise with back arthritis?

Yes, and staying active is important. Gentle exercise like walking, swimming, or water aerobics strengthens muscles that support your spine and can reduce pain. Avoid high-impact activities and heavy lifting. A physical therapist can show you which exercises are safe for your specific situation.

What is the difference between back arthritis and a herniated disc?

Back arthritis is wear and tear of the joints in the spine. A herniated disc is when the cushioning material between vertebrae bulges or ruptures, often pressing on a nerve. They can occur together, and both cause back pain. Imaging and a doctor's examination can tell them apart.

Will injections make my arthritis worse?

No. Steroid injections reduce inflammation temporarily but do not damage the joint or speed up arthritis progression. They are a way to manage pain while you do physical therapy and stay active, which can actually slow decline.

How long does recovery take after spine surgery?

Most people need four to six weeks before returning to light activities and two to three months before returning to normal activity. Full recovery can take six months or longer. Your surgeon will give you specific restrictions and a timeline based on the type of surgery you had.
