Ischial bursitis (ischio-gluteal bursitis) is a condition of inflammation of the bursa, which lies between the ischial tuberosity and the gluteus maximus muscle. It presents with gluteal pain or posterior upper thigh pain following exercise or sitting for a long time. This activity reviews the evaluation and management of ischial bursitis and highlights the role of the interprofessional team in the recognition and management of this condition.


  • Describe the recommended management of ischial bursitis.
  • Outline the typical presentation of a patient with ischial bursitis.
  • Review the pathophysiology of ischial bursitis.
  • Explain the interprofessional team strategies for improving care coordination and communication regarding the management of patients with ischial bursitis.


Ischial bursitis, also known as ischio-gluteal bursitis or "weaver's bottom," is a condition where the bursa that lies between the ischial tuberosity and the gluteus maximus muscle becomes inflamed. This bursa is present physiologically to reduce the amount of frictional force generated between the gluteal muscle and the ischial tuberosity that otherwise might become damaged or irritated by this contact. This inflammation of the bursa most commonly results from prolonged pressure on the ischium, as occurs in sitting for extended periods or from the repeated movement of the gluteus maximus muscle in such activities as bicycling. These activities cause an inflammatory reaction that results in swelling and tenderness over the lower buttock and upper posterior thigh. Many other differential diagnoses have common presentations, such as sciatica and tendonitis of hamstring muscles.[1]


The origin of ischial bursitis is apparent in the original name of the condition, "weaver's bottom."[2] This condition was first seen in workers that sat for long periods of time on hard surfaces. Another colloquial name for this condition is "tailor's bottom." Ischial bursitis may occur in various conditions, much like many other bursal inflammations. Autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and scleroderma, among others, have been shown to cause bursitis. This inflammation may result from uremia seen in conditions such as gout and chronic kidney disease. The ischial bursa is a deep bursa, meaning it is less susceptible to the contiguous spread of infectious organisms. Although rare, infectious etiologies of ischial bursitis include septicemia and septic arthritis. Direct inoculation of the bursa by bacteria would be very rare due to its location in the body.[2]


Ischial bursitis is a relatively uncommon clinical condition. Although the diagnosis is often unrecognized, it may present in patients of all ages.  Bursitis as whole accounts for less than one percent of total primary care visits. This condition is most common in persons with sedentary careers with constant irritation of the ischial bursa due to prolonged periods sitting on hard surfaces, which gives this condition its colloquial name, “weaver’s bottom.” Weaving as a profession has been around since approximately 6000 BCE, and people have been suffering from this condition for as many years.[3]


Bursa comes in a variety of forms: adventitious, subcutaneous, submuscular, and synovial. The ischial bursa is synovial, meaning it is composed of a fatty connective tissue capsule filled with synovial fluid. When infection or irritation occurs, cells of the synovia proliferate, resulting in increased production of synovial fluid. Inflammatory mediators such as cyclooxygenase, cytokines, and metalloproteases mediate this process. The result is a thick fluid-filled cavity with high amounts of fibrin, resulting in the formation of granulation tissue.[4] Over time, this tissue will gradually interfere with the normal motion and activity of the surrounding tissues, whether they are muscle, bone, or tendon.

History and Physical

Patients will present with gluteal pain and/or upper posterior thigh pain following prolonged sitting or exercise. The patient will most commonly complain of a low grade, pinpoint, and aching pain worsened by sitting down or stretching the gluteus maximus muscle. Patients may complain of problems sleeping because of the pain. Patients also may have reduced mobility and swelling associated with this condition. On physical exam, the examiner may note tenderness over the buttock. Patients may have pain with passive flexion at the hip joint. The patient also may have an inability to extend the hip. The patient may feel pain with stretching. There may be overlying erythema, although less this is commonly associated with ischial bursitis. If erythema is a major part of the presentation, this may point to other etiologies such as cellulitis or septic joint.


On evaluation, most cases can be diagnosed and treated clinically without the need for further testing. Most cases of ischial bursitis are self-limiting and will resolve with time. Blood work should is only necessary if an infection or autoimmune condition is suspected. In the case of bursitis, lab values will most likely be within the normal range. If other conditions are suspected, such as a septic joint, this may indicate joint aspiration and the initiation of antibiotic treatment. MRI is sensitive for bursitis but is expensive and unnecessary most of the time when diagnosing and treating ischial bursitis. This test is only necessary if there are other possible differentials, such as tumors. Ultrasound, similarly, is unnecessary performing unless aspiration, then it is useful to guide the procedure, ensuring aspiration occurs in the appropriate location.[2]

Treatment / Management

Initially, the general nature of this condition should indicate minor, low-cost interventions such as NSAIDs and rest. If the condition persists, the clinician may consider therapeutic mixed steroid and anesthetic injections. Only if the condition continues to be resistant or other etiologies are indicated by the workup for this patient presentation should more invasive and/or expensive test be used. Treatment of ischial bursitis is relatively symptom driven. Primary treatment is lifestyle modification by stopping the activity that caused bursitis in the first place, whether it was a physical activity or sitting for long periods on hard surfaces. Nonsteroidal anti-inflammatory drugs such as naproxen work well to decrease inflammation, and a regimen of daily intake for two weeks may help prevent further inflammation. Naproxen also may help reduce the pain associated with this condition.

Cold compresses may help in the short term to minimize pain from swelling. If the pain is unbearable or unrelenting, an intrabursal corticosteroid injection with lidocaine is an option. The lidocaine will help by providing immediate relief from the pain by blocking the sodium channels in the surrounding tissue, inhibiting the transmission of the pain signal. The corticosteroid will provide prolonged anti-inflammatory protection by inhibiting the inflammatory mediators. Patients will most likely be symptom-free within days to weeks without treatment.[4] The rate of recovery is highly dependent on the severity of patient symptoms and the modality of therapy chosen. Recurrence is likely without a lifestyle change.[2]

Differential Diagnosis

Many conditions present similarly, and the clinician will need to rule these out to determine the final diagnosis of ischial bursitis. X-ray imaging of the hip and lumbar spine may help rule out referred pain from these regions from degenerative joint disease, arthritis, or other conditions. A physical exam will help differentiate ischial bursitis from muscle-related causes for the pain, whether it is a tear of the muscle body or other conditions.


Unless the etiology of irritation on the ischio-gluteal bursa is accurately identified and addressed, ischial bursitis will usually not spontaneously remit. The pain may abate with a period of lay-off or treatment, but reinitiating activity will still lead to excessive friction on the bursa, causing inflammation and the recurrence of pain.


Ischial bursitis can result in problems with:

  • Walking
  • Running
  • Sitting
  • Stretching

SUbsequent avoidance of activity and exercise may lead to overall reconditioning and negatively affect other conditions that respond well to or are prevented at some level by exercise and activity.

Deterrence and Patient Education

Patients with ischial bursitis should not continue with activities that aggravate their pain or exacerbate it. These activities cause increased friction on the bursa, resulting in further irritation and inflammation, and potentially delaying recovery.

Enhancing Healthcare Team Outcomes

Ischial bursitis is a rare disorder that is encountered by the primary care provider, nurse practitioner, internist, or the sports physician. The diagnosis is clinical but may require exhaustive workup to rule out other disorders. The treatment is usually conservative with rest, pain relief, and physical therapy.[5][6]

Cold compresses may help in the short term to minimize pain from swelling. If the pain is unbearable or unrelenting, an intrabursal corticosteroid injection with lidocaine may provide relief. The lidocaine will help by providing immediate relief from the pain by blocking the sodium channels in the surrounding tissue, inhibiting the transmission of the pain signal.[2]

It is essential to educate the patient on lifestyle changes, including weight loss and regular exercise. Occupational and/or physical therapy may be of value in this regard. Recurrences are common in patients who lead a sedentary lifestyle.[7]
