Bursitis
Inflammation of fluid-filled sacs cushioning joints.
TL;DR
Inflammation of a bursa — the fluid-filled cushion near a joint — causing localized pain and swelling, usually from repetitive pressure or overuse. Most cases resolve with rest, ice, and activity modification.
Overview
Bursitis is inflammation of a bursa, one of the small fluid-filled sacs that reduce friction between tendons, muscles, and bone around joints. The usual suspects are the shoulder (subacromial), elbow tip (olecranon), hip (trochanteric), and kneecap (prepatellar — housemaid's knee). Causes are predominantly mechanical: repetitive motion, prolonged kneeling or leaning, and direct trauma. Crystal disease (gout) and infection (septic bursitis — red, hot, feverish) account for important minorities. Typical cases present with localized pain on movement or pressure and sometimes visible swelling. Management is conservative for most: relative rest, ice, NSAIDs, and correcting the mechanical trigger; persistent cases may warrant aspiration or corticosteroid injection.
Common Symptoms
- •Localized pain and tenderness over the affected joint
- •Pain worse with movement or direct pressure (lying on the hip, leaning on the elbow)
- •Visible swelling — a goose-egg over the kneecap or elbow tip
- •Warmth and redness (raises concern for infection)
- •Reduced range of motion in the adjacent joint
Common Causes
- •Repetitive motion or overuse (throwing, scrubbing, gardening)
- •Prolonged pressure — kneeling, leaning on elbows, lying on one hip
- •Direct trauma to the bursa
- •Gout or pseudogout (crystal inflammation of the bursa)
- •Bacterial infection through skin breaks (septic bursitis) — the dangerous variant
Root Causes
Bursitis is a mechanical-load problem: the bursa inflames when friction or pressure exceeds its tolerance. Lasting resolution requires fixing the load — technique changes, padding, ergonomic adjustments, strength and flexibility work around the joint — not just quieting the inflammation and returning to the same stimulus.
How It's Diagnosed
Diagnostic Markers
- Clinical exam: focal tenderness and swelling over a known bursa site
- Ultrasound confirming fluid-filled bursa when needed
- Aspiration with fluid analysis if infection or crystals are suspected
- X-ray to exclude bony causes in persistent cases
- Fever, spreading redness, or severe pain → urgent assessment for septic bursitis
When to See a Doctor
See a clinician for bursitis with fever, spreading redness, severe pain, or inability to move the joint (possible infection — same-day assessment). Also seek care if swelling persists beyond 2–3 weeks of conservative care or recurs repeatedly.
Supplements Studied For This
Diet & Lifestyle
Suggested Pattern
No diet treats bursitis directly. An anti-inflammatory pattern supports the background environment, and weight management reduces load on hip and knee bursae. Gout-related bursitis specifically improves with gout-directed diet and urate management.
Eat more
- Anti-inflammatory pattern: oily fish, olive oil, vegetables, berries
- Adequate protein for tissue repair
- Hydration — relevant for gout-associated bursitis
- Calcium and vitamin D for underlying bone health
Avoid
- For gout-associated bursitis: organ meats, excess beer and spirits, sugary drinks
- Excess alcohol generally (inflammation, gout risk)
- No specific food exclusions are evidence-based for mechanical bursitis

Frequently Asked Questions
Who It Affects
Bursitis is among the most common musculoskeletal complaints; trochanteric pain syndrome alone affects up to 1 in 4 adults over 50 at some point. Olecranon and prepatellar bursitis cluster in trades involving kneeling and leaning.
Risk rises with age and repetitive occupational or athletic load. Trochanteric bursitis is notably more common in women and in people with hip osteoarthritis or leg-length differences.
Quick Facts
- •Most cases resolve in 2–6 weeks with load modification
- •Red-hot swollen bursa + fever = possible infection, same-day care
- •Steroid injections help persistent cases but weaken tissue if repeated often
- •The real cure is changing what loaded the bursa
Lifestyle Tips
- •Modify the trigger: kneeling pads, elbow rests, varied technique — the fix is mechanical
- •Ice in the first 48–72 hours; relative rest, not total immobilization
- •Use NSAIDs short-term if appropriate for you; topical forms work for superficial bursae
- •Strengthen and stretch around the joint once acute pain settles — recurrence prevention is muscular
- •Do not inject or drain at home — septic bursitis risk is real
