If you've ever felt pain in the hip, pain in the center of the butt, or pain down the back of the leg, you likely are suffering, at least partially, with piriformis syndrome. The piriformis is a muscle which runs from your sacrum (mid-line base of spine) to the outer hip bone (trochanter). This muscle truly works overtime on anyone who runs at all. The muscles in and around the gluteal region help with three areas: 1) rotation of the hip and leg, 2) balance while one foot is off the ground, and 3) stability for the pelvic region. Needless to say, all of these characteristics are needed by runners. Conclusion--the piriformis muscle is pretty important for all of us.

Injuries to the Piriformis

This muscle is a prime candidate for repetitive motion injury (RMI). RMI occurs when a muscle is asked to perform beyond its level of capability, not given enough time to recover, and asked to perform again. The typical response from a muscle in this situation is to tighten, which is a defensive response. This tightness, however, manifests itself in several ways to a runner.

The first symptom suggesting piriformis syndrome would be pain in and around the outer hip bone. The tightness of the muscle produces increased tension between the tendon and the bone which produces either direct discomfort and pain or an increased tension in the joint, producing a bursitis. A bursitis is an inflammation of the fluid filled sac in a joint caused by an elevation of stress and tension within that joint.

The second symptom suggesting piriformis syndrome would be pain directly in the center of the buttocks. Although this is not as common as the other two symptoms, this pain can be elicited with direct compression over the belly of the buttocks area. A tight muscle is a sore muscle upon compression due to a reduced blood flow to that muscle.

The third symptom suggesting piriformis syndrome is a sciatic neuralgia, or pain from the buttocks down the back of the leg and sometimes into different portions of the lower leg. The sciatic nerve runs right through the belly of the piriformis muscle and if the piriformis muscle contracts from being overused, the sciatic nerve now becomes strangled, producing pain, tingling, and numbness.

Simple Physiology

Any muscle repetitively used needs to have an opportunity to recover. This recovery can either be on Nature's clock, or can be facilitated and sped up with proper knowledge and treatment. Since the muscle is tightening due to overuse, continued use will only make it worse. This injured muscle needs to relax and have increased blood flow to it for more rapid healing. The tightness also reduces the normal blood flow going to the muscle, reducing the speed with which the muscle can recover. To encourage fresh, oxygen-rich blood to the muscle is the most powerful means of getting the muscle to begin to relax and function normally. Multiple massages per day to this area are greatly encouraged.

The next step in this "recovery" process is to use a tennis ball under the butt and hip area. While sitting on the floor, roll away from the side of involvement and place a tennis ball just inside the outer hip bone under the butt area. As you begin to allow your weight onto the tennis ball, note areas of increased pain and soreness. Trigger points will tend to accumulate in a repetitively used muscle, and until these toxins are manually broken up and eliminated, the muscle will have an artificial ceiling with regard to flexibility potential and recovery potential. So, if it's sore and hurts while you are sitting on it, you're doing a good job. Let the ball work under each spot for fifteen to twenty seconds before moving it to another area. Once you've been on the ball for four to five minutes, put the ankle of the involved leg over the knee of the noninvolved leg (crossing your legs). Now place the tennis ball just inside the outer hip bone again and work the tendon of the piriformis muscle. While this pain is typically excruciating and takes some time to effectively reduce, the benefits here are huge. Be patient, be consistent, and good things will happen.

Additional Treatments

Due to the fact that the sciatic neuralgia and the hip bursitis or tendonitis are both inflammatory in nature, ice, or cryotherapy, over the involved area fifteen to twenty minutes at a time will be beneficial. This should be done multiple times per day.

Stretching of the hip muscles should not be done until the acute pain is gone. Then, begin with gentle stretching, such as the cross-legged stretch, while pulling up on the knee. The muscle should have increased flexibility before an active return to running.

Finally, I always discourage the use of pharmaceutical anti- inflammatories. Not only do they greatly aggravate the intestines, they suggest an artificial wellness that can lead to bigger problems. Proteolytic enzymes, such as bromelain, are both natural and extremely beneficial with no side effects. For more information, visit your health food store or check out Rehab Plus on our website.
