Woman who have hip pain when sitting

There are a lot of possible causes for experiencing hip pain and hip pain can be experienced in different activities such as walking, running, standing, and sitting especially when done in prolonged periods that is nearly disabling. The hip pain can be simple and temporary or can even be a long-term degenerative condition. It is vital to know the different causes of hip pain to know when it is time to seek advice from a medical expert and to get the proper treatment.

Here are some of the common reasons for hip pain when sitting:


Bursitis is the most common cause of hip pain. Bursitis occurs when the bursa, a fluid-filled sac that cushions the hip joint, gets inflamed and irritated. Bursitis of the hip can affect anyone of any age or gender but it frequently affects older individuals and individuals who are involved in sports or other activities with repetitive motions. It can be brought about by an infection, a hip injury, stress on the hip joint, and autoimmune flare-ups. Bursitis of the hip is worst when sitting or lying down on the affected side because the large bursa is located in the outer part of the hip.


Arthritis is the most common reason for hip pain when sitting. It causes pain if you have not moved for a long time because the joints tend to be stiff when not used for a long time.

There are four types of arthritis that can cause hip pain:

  • Hip Osteoarthritis – The cartilage in the hip joint that is supposed to protect the hips during movement becomes thin as one grows old. The thinning of the cartilage causes inflammation and painful rubbing.
  • Rheumatoid arthritis – This is an autoimmune disorder that damages the cartilage of the joints and has a tendency to affect both sides of the body. An individual with this condition experiences pain in both hips that can get worse over time.
  • Psoriatic arthritis – One symptom of this condition is a pain in the hip after lying down or sitting for a long period of time. This is also an autoimmune disorder where the body attacks the healthy tissues in the hip joint.
  • Ankylosing spondylitis – This condition may be genetic in nature but the real cause is still known. What is certain is that this condition causes hip pain while lying down or sitting. It causes stiffness and pain in the spine.


Sciatica is a nerve compression that actually occurs in the lower portion of the back but the pain radiates to the hip up to the legs causing referred pain on the hip. The pain is usually felt when sitting down and when standing up from a sitting position. It can be caused by a back injury, growth spurts, sitting for longer periods of time, repetitive lifting, and injections to the buttocks.

4.Poor Posture

It’s important to maintain a good posture even when sitting down. Body mechanics that are improper can result in hip pain. Improper sitting such as sitting cross-legged, W-sitting, knees pressed tightly together, or one knee over the other tends to pull on the outer hip muscles causing hip pain.

5.Muscle Strain

Any kind of muscle strain can cause hip pain when sitting. Performing any activity that puts a force on the hip strains the muscles surrounding the joint. Muscle strain can be caused by heavy lifting, doing things repetitively, and overworking the muscles.

6.Femoroacetabular Impingement (FAI)

The labrum is a thick cartilage that cushions the head of the femur of the hip joint. It can be torn due to a hip deformity or a hip injury. It is characterized by a stabbing pain in the hip while sitting especially in low seats. Another symptom is a popping in the hip socket when the leg moves. It usually affects those individuals who sit for prolonged periods.

7.Avascular Necrosis

Avascular necrosis is a condition which occurs when there is a loss of blood to the bone which can result in tiny breaks in the bone and collapse of the bone. The blood flow to the bone gets interrupted if the joint gets dislocated or the bone is fractured. This condition usually occurs in the hip.


The synovium is a protective layer for the tendons attached to the hip. The lubricant fluid inside the synovium can be inflamed. Once the tendons near the hip are injured, you can develop tenosynovitis which causes pain when bending or sitting.

9.Legg-Calves-Perthes Disease

Legg-Calves-Perthes Disease is a rare disease that occurs when the blood supply to the ball joint in the hip is temporarily interrupted. The interruption of the blood flow is unexplainable but it causes deformity and degeneration of the ball socket of the hip joint. This condition usually affects kids but is more common in younger boys.
