The condition is cauda equina syndrome. It involves “acute loss of function of the neurologic elements (nerve roots) of the spinal canal below the termination (conus) of the spinal cord,” where the nerves spread out like a horse (equina) tail. Again, this condition causes symptoms in the “saddle” of the body: butt, groin, inner thighs. BACK TO TEXT
Located deep in the front of the hip and connecting the leg, pelvis, and abdomen, the hip flexors— surprise, surprise— flex the hip. But despite being some of the most powerful muscles in our bodies (with a clearly important role), it’s easy to neglect our poor hip flexors— often without even knowing it. It turns out just working at a desk all day (guilty!) can really weaken hip flexors since they tend to shorten up while in a seated position. This tightness disrupts good posture and is a common cause of lower back pain. Weakened hip flexors can also increase the risk of foot, ankle, and knee injuries (especially among runners) Hip muscle weakness and overuse injuries in recreational runners. Niemuth, P.E., Johnson, R.J., Myers, M.J., et al. Rocky Mountain University of Health Professions, Provo, VT. Clinical Journal of Sport Medicine, 2005 Jan; 15 (1): 14-21.. So be sure to get up, stand up every hour or so! And giving the hip flexors some extra attention is not just about injury prevention. Adding power to workouts, working toward greater flexibility, and getting speedier while running is also, as they say, all in the hips The effect of walking speed on muscle function and mechanical energetics.

To do this stretch, sit on the floor with your legs about three or four feet apart, depending on how tall you are. Make sure your toes and knees are pointed straight up. Next, take a deep breath, and on the exhale, slowly fold your upper body forward. Rest your hands on your feet, legs, or the floor in front of you and hold this stretch for five deep breaths.
Please note that none of the above given tips or recommendations substitute medical advice. Important: consult a health professional in case of an injury or if you suspect overuse of joints or a medical condition such as a fracture. A physician should be consulted in those acute cases when the condition is accompanied by reddening, swelling or hyperthermia of joints, ongoing joint trouble or severe pain and/or are associated with neurological symptoms
Even though it seems like your legs are moving forward and backward when you’re running, in reality, the femur (your thigh bone) both rotates and tilts in the hip socket, Kalika explains. It’s the hip adductors—most notably the gluteus medius—that keeps the femur sitting in the socket as designed. (The hip adductors are the muscles that move your legs inward.) Any weaknesses make the joint unstable, and can contribute to poor running mechanics, hip drop (when the pelvis drops to one side), too-narrow stances, and aggravated tissues throughout the entire body, Sauer says.

To complete this stretch, take a knee in front of a wall so that the toes of the leg you have raised are pressing against the wall. Place that same hand against the wall. Reach behind you with your other hand and grab your leg that’s sitting on the floor by the ankle, and bend it back towards your body. Hold this position and lunge forward towards the wall to complete the stretch. Hold this stretch for 10 seconds, then repeat on the other side of your body.
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.
