Bursitis occurs due to inflammation of the bursa, a small fluid-filled sac that cushions and reduces friction between bones, tendons, and muscles.
Persistent pain around the hip or knee may be more than muscle fatigue or strained joints; rather, it is bursitis-one of the common and often less-recognized causes of joint pain. Bursitis involves inflammation of the small, fluid-filled sacs enveloping your joints, cushioning them. These sacs allow for smooth, painless movement by minimizing friction between bones, tendons, and muscles.
If left untreated, early symptoms of bursitis can turn what started as temporary irritation of the bursa into a chronic problem. Knowing what causes hip or knee bursitis, how to recognize its symptoms, and how to treat the problem and prevent it from returning may make a big difference in your road to recovery and long-term joint health.
Bursitis is an inflammation of the bursa, a small, jelly-like sac around joints like the hip, knee, shoulder, and elbow. It acts like a cushion to avoid friction between bones, tendons, and muscles. This produces pain, stiffness, and tenderness when there is irritation or swelling of that sac.
While bursitis can occur at most joints, it is particularly common around the hip and knee because these areas bear much of the body's weight and are subject to a great deal of repetitive motion. The most common types of bursitis include the following:
It can be brought about by various factors, such as repetitive motions or overuse from running, cycling, climbing stairs, and even from just kneeling for long periods of time. These movements, over time, will create enough friction and pressure that the bursa will eventually get irritated.
Direct blows or trauma, such as falling onto your knee or bumping your hip, can also bring on bursitis. Abnormal posture, weak supporting muscles, or tight tendons may put additional stress on the joint and increase the risk of bursitis.
Other times, bursitis results from an infected bursa, due to bacteria gaining entry through a cut or laceration near the joint. In contrast, conditions which may result in recurring bouts of bursitis tend to be those such as rheumatoid arthritis, gout, or diabetes, in which there is increased systemic inflammation or alterations in joint mechanics.
The classic symptom of bursitis is pain around the involved joint. In hip bursitis, it usually occurs on the outer side of the hip, with radiation down the thigh and discomfort lying on this side. Pain in knee bursitis usually occurs at the front or inside of the knee and may be increased by kneeling, bending, or climbing.
Other common symptoms include:
Only in cases where the pain persists for some days and interferes with normal motion would an examination be required, so the professionals can confirm whether it is bursitis or another problem with the joint.
A typical medical workup of bursitis usually consists of a healthcare provider performing a physical examination. The site of pain, tenderness, and swelling is examined, and your range of motion is checked.
Imaging studies can also be ordered by your doctor to exclude other conditions such as arthritis, fractures, or tendon tears. X-rays, MRI, or ultrasound may be ordered. If the suspicion of an infection exists, then bursal aspiration may be performed in which fluid is drawn from the bursa for laboratory analysis. This helps to differentiate between an infectious and a non-infectious cause of inflammation.

Common causes of hip and knee bursitis include overuse, repetitive movements, trauma, or prolonged pressure on the joint.
Fortunately, most cases of hip or knee bursitis will settle well with nonsurgical treatments with early management. The aims of treatment are threefold: control inflammation, reduce pain, and prevent recurrence.
Avoid repetitive movements or high-impact activities in order not to further inflame the bursa. Protective devices, including a cane, padded knee pads, and ergonomic supports, help take pressure off the affected joint while it heals.
Application of ice in the acute inflammatory stage reduces swelling and pain. In contrast, after the acute inflammation has passed, relieving stiffness with heat, such as warm compresses or heating pads, will also encourage blood flow.
Over-the-counter NSAIDs, such as ibuprofen or naproxen, may be used to help reduce pain and inflammation. For cases with severe swelling, injections of corticosteroids can be indicated in order to achieve fast-acting relief. If the bursitis is caused by an infection, antibiotics will be required to kill the bacteria and prevent further complications.
Physical therapy is vital during long-term recovery. Stretching and strengthening exercises promote restoration of flexibility and improvement in joint stability. The therapists will also guide posture correction and gait retraining to avoid recurrence. As your pain improves, you'll resume your usual activities with improved form and control.
In the case of significant swelling with fluid, bursal aspiration may be utilized in order to relieve pressure by aspirating the fluid out of the bursa. Surgical removal of the bursa, or bursectomy, is seldom necessary but can be applicable for chronic bursitis which does not respond to conservative treatments.
The best results are to be expected, and recovery is considerably hastened when treatment is combined with home care.
Always warm up and cool down before every workout or physical activity. Regular stretching and strengthening exercises should be done to strengthen the muscles in the hips and knees. Joints are protected by the use of ergonomic techniques in lifting, climbing, or repetitive of certain movements. Above all, early signs of discomfort must be heeded: the sooner treatment starts, the less chance inflammation has to worsen.

Acute bursitis usually develops suddenly after injury or infection, while chronic bursitis results from repetitive irritation or underlying joint conditions such as arthritis.
Hip or knee bursitis can be painful and limiting, but recovery is very achievable with the proper blend of rest, therapy, medication, and prevention. Paying early attention to root causes and building up joint-friendly habits can keep you active, flexible, and pain-free long into the future. If symptoms persist, seek consultation with a healthcare expert, as timely treatment can make all the difference in preserving your joint health.
1. How long does recovery from hip or knee bursitis take?
Usually 2-8 weeks, depending on the earlier commencement of treatment and whether the inflammation is acute or chronic.
2. Should I exercise with bursitis?
Yes, but stick to only low-impact exercises like swimming or cycling. Avoid repetitive movements, further aggravating the pain.
3. Is bursitis the same as arthritis?
No, bursitis affects the fluid-filled sacs around the joint, while arthritis is an inflammation of the joint's cartilage and bone.
4. What is the best sleeping position for hip bursitis?
On your back or on your unaffected side. Put a pillow between your knees to help take the pressure off your hip.
5. Does bursitis recur even after treatment?
Yes, if the repetitive stress continues, it can recur. Regular stretching, strengthening, and good posture are helpful in preventing recurrence.
6. When should I consider surgery for bursitis?
When the bursitis does not respond to medication, therapy, or injections after several months of consistent care, then surgery may be considered.
