Keep it a one joint stretch. Many people want to jump right to performing a hip flexor stretch while flexing the knee. This incorporates the rectus and the psoas, but I find far too many people can not appropriately perform this stretch. They will compensate, usually by stretching their anterior capsule too much or hyperextending their lumbar spine.
Tight hamstrings are a common cause of lower back pain, and if you have a desk job, you’re at risk for both. Perform the seated forward fold paschimottanasana several times a day to stretch your shoulders, hamstrings, and spine. Sit on your mat with your legs straight, your feet together and flexed, your torso erect (but not arched), and your chin lifted like you’re proud to be performing this pose (which you should be!). Take a deep breath in, straightening up as much as you can, and then fold forward, walking your hands down the sides of your legs as you lower your torso as far as you can. Hold the pose for 8-10 breaths, and then slowly reverse the movement to raise your torso back up.
A few cancers in their early stages can be hard to tell apart from ordinary back pain — a bone cancer in the vertebrae, for instance — and these create a frustrating diagnostic problem. They are too rare for doctors to inflict cancer testing on every low back pain patient “just in case.” And yet the possibility cannot be dismissed, either! It’s an unsolveable problem.
Why is back pain still a huge problem? Maybe this: “It is extremely difficult to alter the potentially disabling belief among the lay public that low back pain has a structural mechanical cause. An important reason for this is that this belief continues to be regularly reinforced by the conditions of care of a range of ‘hands-on’ providers, for whom idiosyncratic variations of that view are fundamental to their professional existence.”
3. Tendinitis and bursitis Many tendons around the hip connect the muscles to the joint. These tendons can easily become inflamed if you overuse them or participate in strenuous activities. One of the most common causes of tendinitis at the hip joint, especially in runners, is iliotibial band syndrome — the iliotibial band is the thick span of tissue that runs from the outer rim of your pelvis to the outside of your knee.
Preventing hip flexor injury focuses on good flexibility, as well as making sure you warm up before you go full speed. Warm muscles are much less likely to be injured. So take the time to warm up and start slowly before you go all out. A good flexibility program will also help to reduce the tension on the muscles, and reduce your likelihood for injury.
You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
