Tight hip flexors can result in lower back pain, hip pain and injury.  A lot of strain is put on those muscles during activities that involve sprinting and kicking.  For example, runners are more prone to hip flexor injuries because of the small, repetitive movement during running.   But even if you’re not an athlete, hip flexor injuries can occur during everyday activities (for instance, slipping and falling or running to catch a bus).  When those tight muscles are suddenly stretched beyond what they are accustomed to, you might also experience pain in the upper groin region, typically where the hip meets the pelvis.   
Relaxing in a full squat works for releasing the psoas if you’re comfortable. If you’re desperately trying not to fall over backwards, then you’re probably tightening your hip flexors to hold yourself up. This defeats the entire purpose of a resting squat. Grab something like a pillow or a couple books to throw under your heels and see if you can sink down and “rest” into a resting squat. Hold that for a little bit taking some really deep breaths directing the air and pressure of your breath into your back. Then stand up and move around. I bet your hip flexors will feel looser than before the resting squat.

I’m a runner and started experiencing some familiar tightness in my hip and started getting worse everyday I ran. It’s always gotten sore after running for a long extent for the last 4 years or so. I’m glad I found this page because all of these stretches helped me realize what needed to be stretched and how tight I really was! I hope this will fix my overwhelming soreness. Thank you!


How to do it: Put a 20- to 36-inch box behind you. With your feet hip-width apart, lift your leg and place the instep of your rear foot on the bench. Lower your hips toward the floor so your rear knee comes close to the floor, keeping your back straight. As you descend, make sure you don’t bend the torso excessively forward and your front knee does not pass your front toes. Pause when your rear knee is close to the floor and your front quad is parallel with the floor, then drive through your front heel to return to the start position. Repeat this movement, alternating sides each time.
This pose targets your spine, groin, and the backs and insides of your legs. Sit tall with your feet flexed, and your legs straight and spread as wide as possible. Place your palms on the floor in front of you, pressing them into it as you straighten and stretch your spine. Keeping your torso erect, inhale deeply, and then exhale completely, walking your hands forward as you lower your torso as far as you can towards the floor. Stop when you feel a deep stretch in the areas mentioned above. Hold for 8-10 breaths, and then slowly raise your torso back up.
For example, your quadriceps muscles are a group of four that are located at the front of the thigh; one of the group members, the rectus femoris flexes the hip, which brings your lower extremity (thigh, lower leg, and foot) forward, in front of you. On the other hand, your hamstring muscles are located at the back of the thigh. When they contract, they extend the lower extremity, bringing it behind you.
• Rheumatoid arthritis. Rheumatoid arthritis is a chronic inflammatory disease of the joints that occurs when the body’s immune system – which normally protects us from infection – mistakenly attacks the synovium, the thin membrane that lines the joints. Although rheumatoid arthritis most commonly affects the hips, knees, hands, wrists, feet, elbows and ankles, it can also affect the facet joints in the spine, causing pain and, in severe cases, destruction of the joints. This may allow the upper vertebra to slide forward on top of the lower vertebra, a condition called spondylolisthesis. The slipped vertebra may put pressure on the spinal cord and/or the nerve roots where they exit the spine.
There are cases of low back pain that have alarming causes, but it’s rare. Once in a while back pain is a warning sign of cancer, autoimmune disease, infection, or a handful of other scary culprits.7 Over the age of 55, about one in twenty cases turns out to be a fracture, and one in a hundred is more ominous.8 The further you are from 55, the better your odds.

Sciatica refers to back pain caused by a problem with the sciatic nerve. This is a large nerve that runs from the lower back down the back of each leg. When something injures or puts pressure on the sciatic nerve, it can cause pain in the lower back that spreads to the hip, buttocks, and leg. Up to 90% of people recover from sciatica without surgery.
Grade III (severe): A complete tear in your muscle that causes severe pain and swelling and you can't bear weight on that leg, making it difficult to walk. You've also lost more than 50 percent of your muscle function. These injuries are less common and may need surgery to repair the torn muscle. They can take several months or more to completely heal.
