The most effective approach to joint pain relief combines regular exercise, weight management, and anti-inflammatory medication, either topical or oral. No single treatment works best for everyone, but the American College of Rheumatology’s guidelines make strong recommendations for a specific set of options: exercise, weight loss for those who are overweight, oral and topical anti-inflammatory drugs, tai chi, and steroid injections for knee pain. Most people get the best results by layering several of these together.
Exercise Reduces Pain Even Once a Week
Strength training is the single most effective exercise for joint pain, and it works at surprisingly low doses. A cross-sectional study of people with knee osteoarthritis found that resistance training just once a week produced significantly lower pain scores compared to no exercise. Training two or three times a week delivered even greater benefits. Sessions in the study lasted about 50 minutes at moderate intensity, with 8 to 10 exercises performed in 3 sets of 8 repetitions.
Stretching also helps, but it requires more consistency. Pain reduction from stretching only reached significance when done three times a week. Aerobic exercise, interestingly, didn’t show meaningful pain reduction on its own, though it did improve functional independence when performed two to three times weekly. The takeaway: if you can only do one type of exercise, choose strength training. If you can add stretching a few days a week, that’s even better.
Weight Loss Has an Outsized Effect on Knees
Every pound you lose removes roughly four pounds of force from your knees with each step. That ratio, documented in a study of overweight and obese older adults with knee osteoarthritis, means that losing just 10 pounds takes about 40 pounds of pressure off your knee joints during daily walking. Over the course of a day, that adds up to tens of thousands of pounds of cumulative load reduction. For people carrying extra weight, this is one of the most powerful interventions available, and it’s strongly recommended by the ACR guidelines alongside exercise.
Topical Pain Relievers: Effective With Fewer Side Effects
Topical anti-inflammatory gels and solutions (like diclofenac gel, available over the counter in many countries) deliver medication directly to the joint with far less reaching your bloodstream. In a pooled safety analysis comparing topical and oral versions of the same drug, gastrointestinal side effects dropped significantly with the topical form: 25.4% versus 39.0% for oral. Only 5.8% of people using the topical version quit due to stomach-related problems, compared to 14.5% of those taking the oral version.
The ACR strongly recommends topical anti-inflammatories specifically for knee osteoarthritis. They’re a particularly good first choice if you have a history of stomach issues, are over 65, or want to minimize the risks that come with swallowing pain medication daily. The main downside is that topical treatments work best on joints close to the skin surface, like knees and hands, and are less effective for deeper joints like the hip.
Oral Anti-Inflammatories Outperform Acetaminophen
If you’ve been reaching for acetaminophen (Tylenol) for joint pain, you may want to reconsider. A meta-analysis of seven trials found that NSAIDs like ibuprofen and naproxen reduced both resting and walking pain more effectively than acetaminophen. The difference was about 6 points on a 100-point pain scale for both measures. That’s a modest but real advantage, and safety profiles between the two were statistically similar in those trials.
Oral NSAIDs are strongly recommended in the ACR guidelines. They work by reducing inflammation, which acetaminophen does not do. Since joint pain is typically driven by inflammation, this makes NSAIDs a better match for the underlying problem. The tradeoff is that long-term NSAID use raises risks for stomach ulcers, kidney stress, and cardiovascular events, so they’re generally best used at the lowest effective dose for the shortest time needed.
Fish Oil Works, but Dose Matters
Fish oil supplements can meaningfully reduce joint pain and morning stiffness, particularly in inflammatory types of arthritis like rheumatoid arthritis. A 2021 analysis of 70 studies found that fish oil significantly reduced disease activity, pain, and morning stiffness. But the dose makes the difference. Higher doses, above 2,600 milligrams per day of combined EPA and DHA, lowered inflammatory markers like C-reactive protein and allowed some patients to stop taking NSAIDs entirely, with reduced disease activity lasting nearly eight months.
Most over-the-counter fish oil capsules contain around 300 milligrams of EPA and DHA combined, so reaching an effective dose typically requires a concentrated formula or several standard capsules daily. Look for supplements that list the EPA and DHA content separately rather than just “fish oil,” since the active ingredients are what matter.
Glucosamine and Chondroitin: Popular but Unproven
Despite their widespread use, glucosamine and chondroitin don’t appear to work better than placebo. A major network meta-analysis published in The BMJ examined 10 trials involving over 3,800 patients with hip or knee osteoarthritis. Pain reduction on a 10-point scale was 0.4 points for glucosamine, 0.3 for chondroitin, and 0.5 for the combination. None of these differences crossed the threshold for a clinically meaningful improvement. The supplements also had no effect on joint space narrowing, meaning they don’t slow the physical progression of arthritis either.
If you’ve been taking these supplements and feel they help, the placebo effect in joint pain studies is consistently strong. But if you’re deciding where to spend your money, the evidence points toward fish oil, exercise, or topical anti-inflammatories as better investments.
Curcumin Shows Promise With Caveats
Curcumin, the active compound in turmeric, has shown positive results for arthritis pain in clinical trials, with doses ranging from 120 to 1,500 milligrams daily over 4 to 36 weeks. The challenge is absorption. Standard turmeric powder delivers very little curcumin to your bloodstream, so look for supplements formulated with absorption enhancers (often listed as piperine or phytosome technology). Curcumin works by reducing several inflammatory pathways, making it a reasonable add-on for people who want to complement other treatments with a supplement that has genuine anti-inflammatory activity.
Injections: Short-Term Versus Long-Term Options
For knee pain that hasn’t responded well to pills, creams, and exercise, joint injections offer two distinct timelines. Corticosteroid injections provide the fastest relief, peaking around two weeks and outperforming hyaluronic acid injections during that window. But by week four, the two are equivalent. From week 8 onward, hyaluronic acid pulls ahead, with statistically significant advantages at 12 weeks and 26 weeks.
This means corticosteroid shots are best for short-term flare-ups or when you need quick relief for a specific event, while hyaluronic acid injections suit people looking for longer-lasting improvement. Both are options your doctor may suggest after first-line treatments have been tried, and corticosteroid injections for the knee carry a strong recommendation in the ACR guidelines.
Diet Plays a Protective Role
What you eat influences joint pain over time. A longitudinal study following nearly 3,000 people found that those with the highest adherence to a Mediterranean-style diet had a 9% lower risk of developing symptomatic knee osteoarthritis compared to those with the lowest adherence. Among people who already had knee pain, high adherence was associated with a lower risk of pain worsening over a four-year follow-up. The Mediterranean diet emphasizes vegetables, fruits, whole grains, olive oil, fish, and nuts while limiting red meat and processed foods. Its benefits likely come from its overall anti-inflammatory effect rather than any single food.
Combining a Mediterranean-style diet with adequate fish oil intake and maintaining a healthy weight creates a baseline of lower systemic inflammation, which makes every other treatment on this list work a little better.
