Because the human hip joint is made up of so many different components, it has a lot of potential failure spots – and those failures can cause a lot of pain. Hip discomfort can be caused by a variety of factors, including: 

• Arthritis can cause chronic joint inflammation, discomfort, and stiffness in the hip. Arthritis comes in numerous forms, the most prevalent of which being osteoarthritis (degeneration of the joint cartilage). 
• Bursitis– Your hip joint has bursae, which are fluid-filled sacs that reduce friction between tendons and bones. However, if these bursae are subjected to too much contact, they can become inflamed and painful, resulting in bursitis. 
• Tendinitis is a condition in which one or more tendons become inflamed. This can be a one-time occurrence or a long-term problem. 
• Sciatica is a neurological condition characterized by a pinched nerve, most commonly the sciatic nerve or its nerve roots. Because the sciatic nerve travels through the hip and leg, referred pain in the hip is possible. 
• A sprain or other type of acute injury– A sprain occurs when a ligament is stretched or torn. When you twist your hip or shift direction while your foot is planted, you are likely to have an acute injury. A labral tear is an acute hip injury that involves damage to the ring of cartilage that surrounds the socket. 
• Overuse– Overuse can cause progressive deterioration to any joint, including the hip, as well as persistent pain. Muscle tension and tendinitis can be caused by repetitive activities in your chosen profession or sport.
