Self-care guide
Knee osteoarthritis pain
Pain and stiffness caused by osteoarthritis of the knee, typically worse with joint use and associated with reduced mobility or function.
Step 1 · First-line care
What to do first
Exercise, strengthening, continued physical activity, and weight management when appropriate are core long-term treatments. Topical NSAIDs and other conventional pain-management options generally have stronger evidence than herbal approaches. Labeled topical capsaicin cream is an optional adjunct for some adults with established knee osteoarthritis pain.
Step 2 · Safety
When to get medical help
Seek urgent medical help for very severe knee pain, inability to move or bear weight, marked swelling or deformity, locking or giving way, or a hot/red knee with fever or feeling unwell.
Extra caution: Do not apply capsaicin to broken, inflamed, or irritated skin, near eyes or mucous membranes, or immediately before/after heat exposure. Older adults, people with neuropathy or impaired skin sensation, and people with uncertain diagnosis may need clinician review before self-treatment.

Turmeric
Oral turmeric or curcumin supplements for knee osteoarthritis pain may provide relief of osteoarthritic pain of the knee.
What does this evidence mean?
Systematic reviews and meta-analyses of small, heterogeneous randomized trials suggest possible short-term improvements in pain or function with some oral Curcuma longa/curcumin extracts in knee osteoarthritis. Results are formulation-specific and certainty is limited by heterogeneity, risk of bias, and limited long-term safety data; evidence does not establish benefit for ordinary turmeric foods or tea.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
For ongoing support
These options are better suited to regular or longer-term use than to quick symptom relief.
Capsaicin
Adjunctive relief of pain from established knee osteoarthritis using a labeled topical capsaicin cream; not a claim for oral cayenne, chili-containing food, supplements, essential oils, or homemade rubs.
How it is used: Use only a labeled topical capsaicin product and follow its directions. A commonly studied regimen was 0.025% cream applied four times daily for four weeks, but product labeling should control actual use. Wash hands after application and avoid eyes, mucosa, broken skin, and external heat.
What does this evidence mean?
Topical capsaicin can reduce knee osteoarthritis pain for some people when used regularly, although local burning or stinging is common and benefit varies between individuals.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
