Bursitis: Why a Joint Gets Swollen and Sore, and When It Needs a Doctor

What a bursa does

Bursae are small, flat, fluid-filled sacs that sit between bone and the muscles or tendons moving over it. They reduce friction. When one is irritated, from repeated pressure, repetitive motion, or an injury, it can swell and become tender. That is bursitis.

Where it shows up

Bursitis can occur wherever there is a bursa, but a few places stand out:

• The shoulder, often with overhead reaching
• The outer hip, which hurts when lying on that side
• The elbow, from leaning on a desk or a table
• The knee, from kneeling on hard surfaces
• The heel, from shoes that rub the back of the foot

What it feels like

Typical signs include tenderness over the joint, swelling that may feel puffy or warm, pain when you press on it or lie on it, and pain with certain movements. It can come on suddenly after a bump or gradually after weeks of repetitive pressure.

When it is not just bursitis

A bursa can become infected. Fever, spreading redness, or marked heat around a swollen joint needs prompt medical attention, and should not be treated at a clinic like ours. A very swollen, painful joint with no clear cause is another reason to be seen first, because other conditions, including gout and infection, can look similar.

Bursitis, tendonitis, or both?

Because the two sit side by side, they are often confused and often occur together. If a certain movement provokes sharp pain, a tendon may be involved. If pressure on the swollen area is the main problem, the bursa may be. Your clinician can usually tell from an exam, and sometimes imaging helps.

Small things people try

Many people reduce the pressure or repetition that irritated the bursa to begin with, such as padding the elbow, avoiding kneeling, or changing sleep position. Whether those suit you depends on the cause, so ask your doctor, particularly if the swelling is large or the pain is severe.

Why bursitis tends to return

If the thing that irritated the bursa is still there, kneeling on a hard floor, leaning on an elbow, repetitive overhead work, the bursa can flare again. Spotting and changing that pressure or repetition, with your clinician's input, is often as important as how the flare is calmed. Keep notes on what you were doing before each flare.

Questions worth asking

Whether you see your doctor first or come to us, it helps to ask what is causing the swelling, whether anything about it needs to be ruled out, what to avoid in the meantime, and what should prompt you to call sooner. Write the answers down, because it is easy to forget details once you leave the appointment.

If your clinician suggests ice or cold therapy

Ice is the best-known form of cold therapy, and many clinicians suggest it for sore, irritated areas. HPC is also a form of cold therapy, applied differently: high-pressure CO₂ rapidly cools the skin over the area, with an intense cold that passes quickly. A treatment takes about 3 to 6 minutes per area, where an ice pack session is often 15 to 20 minutes.

If your doctor has recommended ice or cold therapy for your problem, ask whether HPC may be a good fit. Results vary, and HPC is not a substitute for medical care.

What a visit with us looks like

Every visit starts with a free consultation. We ask where it hurts, what you have been told it is, what you have already tried, and whether anything about your health or history means we should not treat. If you are comfortable and it is appropriate, treatment can be done in the same session.

Treatment itself is brief. High-pressure CO₂ is used to rapidly cool the skin over the swollen, sore joint, usually about 3 to 6 minutes per area, and a first visit typically takes 10 to 20 minutes including the consultation. There are no needles and no medication. Most people describe an intense cold that passes quickly. Same-day appointments are often available at our Mineola and Rockville Centre locations.

How many visits, and what about the next flare?

For most people, we recommend an initial series of four to five sessions, then we check how you are doing. Many patients report relief after one or two visits, although individual responses may vary. After the series, we suggest watching to see whether and when the pain returns.

If it does come back, we suggest coming in at the first sign instead of waiting for it to build. Many times a tune-up of 1 or 2 sessions is enough. Discounted packages are available at our Rockville Centre location if you expect to come in more than once.

How High-Pressure Cryotherapy may fit

HPC uses high-pressure CO₂ to rapidly cool the skin over the joint. It may help settle pain and inflammation around it. The underlying cause and how long it has been irritated shape the outcome.

HPC treats the swollen, sore area rather than the cause, and for many people it may help manage inflammation and symptoms.

HPC is not a substitute for medical care and does not replace a diagnosis.
