Ligaments connecting your back to your pelvis: Straining the ligaments around your buttocks and pelvis may result in this type of pain. This area can also be referred to as the sacro-iliac joint. Due to this area linking your lower back and hip you may feel your pain from your lower back through to your hip. Treatment in this presentation should be primarily to the ligament that is strained and addressing posture as well as back stretching exercises when indicated.
The piriformis muscle connects the top of the femur to the spine, and it’s the main one that supports the outward movement of the hip, upper leg, and foot. The sciatic nerve can sometimes pass through this muscle and thus cause sciatica symptoms, otherwise known as piriformis syndrome, characterized by pain in the lower back and hips, poor movement, and balance. Therefore, the main cause of sciatica is the swelling or constriction of the piriformis muscle, but it can also be a result of some other factors as well.
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
