Is It Bursitis? Why Your Joint Is Inflaming + Medically Approved Next Steps

Painful, warm swelling around a shoulder, elbow, hip, knee, or heel that worsens with movement is often bursitis from repetitive motion, pressure, injury, or conditions like gout or rheumatoid arthritis, though infection must be ruled out if there is fever, rapid redness, or severe tenderness. There are several factors to consider, and other problems can mimic bursitis, so diagnosis may need an exam plus imaging or fluid testing.

Initial next steps are rest, ice 15 to 20 minutes 2 to 3 times daily, short-term NSAIDs if safe, gentle motion, compression or elevation when appropriate, and physical therapy, with steroid injection or antibiotics when indicated. For red flags or symptoms lasting over 1 to 2 weeks, talk to a clinician and see the complete guidance below.

Is It Bursitis? Why Your Joint Is Inflaming + Medically Approved Next Steps

If your joint feels swollen, warm, or painful—especially when you move—it's natural to wonder what's going on. One common cause of joint inflammation is bursitis. While it's often manageable, it can be uncomfortable and sometimes signals a more serious issue.

Here's what you need to know about bursitis, how to recognize it, and what medically approved next steps to take.


What Is Bursitis?

Bursitis is the inflammation of a small, fluid-filled sac called a bursa. Bursae act as cushions between bones, tendons, and muscles. They reduce friction and help joints move smoothly.

When a bursa becomes irritated or inflamed, it fills with excess fluid. That's when you start to feel:

  • Pain
  • Swelling
  • Warmth
  • Limited movement

Bursitis most often affects the:

  • Shoulder
  • Elbow
  • Hip
  • Knee
  • Heel

It can develop suddenly (acute bursitis) or gradually over time (chronic bursitis).


Why Is Your Joint Inflamed?

Bursitis happens when a bursa becomes irritated. Common causes include:

1. Repetitive Motion

Repeated movements—like throwing, kneeling, typing, or lifting—can irritate a joint over time.

2. Prolonged Pressure

Leaning on your elbows or kneeling on hard surfaces can trigger bursitis.

3. Injury or Trauma

A direct blow to a joint may cause immediate inflammation.

4. Infection (Septic Bursitis)

Sometimes bacteria infect the bursa. This is more serious and requires prompt medical care.

5. Underlying Medical Conditions

Certain conditions increase risk, including:

  • Rheumatoid arthritis
  • Gout
  • Diabetes
  • Thyroid disorders

If you're experiencing warm joints and want to understand what might be causing your symptoms, a free AI-powered symptom checker can help you identify possible conditions and determine whether you need to see a doctor.


Signs and Symptoms of Bursitis

Bursitis symptoms vary depending on location and severity, but commonly include:

  • Localized pain that worsens with movement or pressure
  • Swelling around the joint
  • Warmth or redness
  • Stiffness
  • Reduced range of motion

The pain from bursitis is often described as dull or achy. In shoulder bursitis, pain may worsen when lifting your arm. In hip bursitis, discomfort may spread down the thigh.

Signs of Possible Infection

Seek medical care promptly if you notice:

  • Fever
  • Chills
  • Rapid swelling
  • Intense redness
  • Severe tenderness
  • Skin that feels hot to the touch

Infectious bursitis requires antibiotics and sometimes drainage. It is not something to ignore.


How Is Bursitis Diagnosed?

A healthcare provider typically diagnoses bursitis through:

  • Physical exam
  • Review of your symptoms
  • Discussion of recent activities or injuries

In some cases, additional tests may be needed:

  • Ultrasound or MRI to confirm inflammation
  • Fluid aspiration (removing fluid from the bursa) to check for infection or gout
  • Blood tests if an underlying condition is suspected

Diagnosis is important because other joint conditions—like arthritis, tendon injuries, or joint infections—can mimic bursitis.


Medically Approved Next Steps

Most cases of bursitis improve with conservative treatment. Here's what doctors commonly recommend:

1. Rest the Joint

Avoid activities that worsen the pain. This allows inflammation to settle.

However, don't completely immobilize the joint unless instructed. Gentle movement prevents stiffness.

2. Ice Therapy

Apply an ice pack for:

  • 15–20 minutes
  • 2–3 times daily

Ice reduces swelling and pain, especially in early stages.

3. Anti-Inflammatory Medication

Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, may reduce pain and swelling.

Always:

  • Follow dosing instructions
  • Check with a doctor if you have kidney disease, stomach ulcers, heart conditions, or take blood thinners

4. Compression and Elevation (When Appropriate)

For knee or elbow bursitis, gentle compression and elevating the limb may reduce swelling.

5. Physical Therapy

A physical therapist can:

  • Improve flexibility
  • Strengthen surrounding muscles
  • Correct posture or movement patterns
  • Reduce recurrence risk

This is especially helpful for shoulder and hip bursitis.

6. Corticosteroid Injections

If pain persists, a doctor may inject corticosteroids directly into the bursa. This often provides fast relief, but repeated injections are generally limited.

7. Antibiotics (If Infected)

If septic bursitis is diagnosed, antibiotics are necessary. Sometimes the bursa must be drained.


How Long Does Bursitis Last?

With proper care:

  • Acute bursitis often improves within a few weeks
  • Chronic cases may take longer and require ongoing therapy

If symptoms last more than a few weeks despite rest and treatment, follow up with your doctor. Persistent inflammation may indicate another underlying condition.


When Should You Speak to a Doctor?

While many cases are mild, some require medical attention.

Speak to a doctor promptly if you have:

  • Fever
  • Rapid swelling
  • Severe pain
  • Joint warmth with systemic symptoms
  • Pain that interferes with sleep
  • No improvement after 1–2 weeks of home care
  • A weakened immune system or diabetes

If you suspect infection or anything that could be serious or life-threatening, seek immediate medical care.


Can Bursitis Be Prevented?

You can lower your risk by:

  • Warming up before exercise
  • Using proper lifting technique
  • Taking frequent breaks from repetitive motions
  • Using knee pads when kneeling
  • Maintaining a healthy weight
  • Strengthening supporting muscles

Small adjustments in daily habits can significantly reduce recurrence.


Is It Definitely Bursitis?

Not necessarily.

Other conditions can cause joint warmth and inflammation, including:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Gout
  • Tendonitis
  • Joint infection
  • Autoimmune disorders

That's why it's important not to self-diagnose. A proper evaluation ensures you get the right treatment.

If you're noticing warm joints along with pain or swelling, using a symptom checker can help you better understand potential causes and prepare for a more informed conversation with your healthcare provider.


The Bottom Line

Bursitis is a common cause of joint inflammation, especially in the shoulder, hip, knee, and elbow. It typically develops from repetitive movement, pressure, injury, or underlying conditions.

Most cases improve with:

  • Rest
  • Ice
  • Anti-inflammatory medication
  • Physical therapy

However, infection and other serious joint conditions can mimic bursitis. Persistent, severe, or systemic symptoms should never be ignored.

If you're unsure what's causing your joint inflammation, take action early. Monitor your symptoms, reduce strain on the joint, and most importantly—speak to a doctor about anything that could be serious, life-threatening, or not improving as expected.

Getting clarity early can prevent complications and help you recover safely and confidently.
