Everything You Need to Know About Ischiogluteal Bursitis

What is Ischiogluteal Bursitis?

Ischiogluteal bursitis is when the bursa located between the sit bone (ischial tuberosity) and the gluteal muscles becomes inflamed or irritated. This small, fluid-filled sac is meant to reduce friction between tissues, but when it’s aggravated, often from sitting too long or overuse, it can cause buttock pain, especially when sitting or stretching the hamstring.

An analogy…

Think of a bursa like a small water balloon cushioning your muscles from the bone. If you sit or press on it too much, it gets squashed and inflamed, like sitting too long on a bruise.

What causes ischiogluteal bursitis?

The ischial bursa lies between the ischial tuberosity (your “sit bone”) and the gluteus maximus muscle. It becomes inflamed from repetitive friction or direct pressure, especially with activities that involve prolonged sitting, running, or hamstring stretching. This leads to pain, swelling, and discomfort over the lower buttock.

What are the signs and symptoms of ischiogluteal bursitis?

Pain in the lower buttock, near the sit bone
Worsens with sitting, especially on hard surfaces
Pain with walking, running, or stretching the hamstrings
Tenderness over the ischial tuberosity
Pain may feel deep and dull, and sometimes mimic hamstring origin tendonitis

What tests are used to diagnose on ischiogluteal bursitis?

Palpation: Direct pressure over the sit bone reproduces symptoms

Stretching tests: Pain when stretching the hamstrings

How long does ischiogluteal bursitis take to heal?

Mild cases can improve in 2 to 4 weeks with rest and modification. More stubborn or chronic cases may take 6 to 8 weeks. Severe or misdiagnosed cases may persist for several months if not properly managed.

How does ischiogluteal bursitis happen?

Prolonged sitting on hard surfaces
Direct trauma to the buttocks
Tight hamstrings pulling on the bursa
Weak glutes or poor posture when sitting or standing
Running or long-distance walking with poor technique
Overuse or sudden increase in physical activity

What treatment can help ischiogluteal bursitis?

Rest from aggravating activities
Ice application in early stages to reduce inflammation
Manual therapy (e.g. massage, dry needling, soft tissue release)
Postural correction and sitting modifications
Stretching and strengthening exercises to address muscular imbalances

What exercises or stretches can I do for ischiogluteal bursitis?

Gentle hamstring and glute stretches
Glute activation exercises
Core stability drills
Hip and postural strengthening

What products can help with ischiogluteal bursitis?

Piriformis stretch

Lie on your back and bend your affected knee.
Cross this leg over your other knee, placing the outside of your ankle just above the knee of your good leg.
Let the knee on your affected leg drop out to the side, and bend the good leg, sliding your heel towards your buttocks.
You may feel a stretch through your affected buttock.
To increase this stretch, interlace your fingers behind the thigh of your good leg, and pull your thigh in towards you, lifting the foot off the ground.
To increase this stretch further still, push your elbow into the thigh of your affected leg.
Hold this position.

Glute stretch – supine

Start position is lying on the back with the legs bent and the feet on the floor.
Lift one leg and cross that ankle over the opposite knee.
Reach between the legs grasping the back of the knee of the lower leg and then pull both legs in towards the chest.
The non-stretch leg should exert a slight pressure that assists in pushing the crossed leg upwards toward the chest.
Hold for as long as prescribed.

Hip extension and abduction raises in side lying

Lie down on your good side and roll your hip forward.
Use your elbows to support you.
Extend the upper leg straight back and rotate your foot down towards the floor. Flex your foot and lift the heel towards the ceiling, while keeping the extended leg straight.
Note that your leg is being lifted at an angle.
Keep your toes pointed down toward the floor.
Steadily return the leg to the starting position.
