Sciatica, Piriformis Syndrome, and Other Pains in the Backside

Updated: Sep 23, 2018

There are plenty of things daily that are virtual pains in the butt and no amount of massage, ice, or analgesics will make them go away. Some of you, however, have actual pain in the buttocks along with numbness, tingling and pain that can travel down the back of the leg and calf all the way to the foot. These symptoms are typically tossed into the general classification of sciatica but there are a number of musculoskeletal problems that can cause these sensations. Many people assume the problem is a bulging disc in the vertebrae of the low back but there are tight muscles, weak muscles, and trigger points that may cause the same problems.


The sciatic nerve is a combination of smaller nerves that arise from between the last two lumbar vertebrae and some that arise from the sacrum. Its function is to send sensory information from the buttocks, back of the thigh, calf, and foot to the brain and carry motor impulses from the brain to the muscles of the leg via the spinal cord. When you feel your foot being tickled or you contract your hamstrings to flex your knee, the information is traveling through the sciatic nerve.


Causes and Treatment of Sciatic Nerve Problems:

Impingement:

Nerves have to travel between and around our muscles and bones to reach their destinations. Any time these tissues entrap or "pinch" a nerve it will cause the typical symptoms of pain, tingling, and numbness as well as weakness in muscles served by that nerve. The sciatic nerve can be impinged anywhere along its length but the most common areas are at the vertebrae of the low back and beneath the piriformis muscle in the buttocks.


· Lumbar Vertebrae

The rubbery shock-absorbing discs between vertebrae make space for the nerves to exit the spinal cord. Several things can happen in this area that can put pressure on the nerve roots:


o Herniated or bulging discs press on the nerve

o Thinning discs narrow the space between bones

o Bone spur growth may impinge the nerve


If the nerve is being pinched between two vertebrae regardless of the cause, symptoms will affect very specific areas of the leg and foot. Because the sacrum is made up of fused vertebrae there are no discs to herniate and cause symptoms.


Treatment depends on the cause. Surgery may be required to stabilize the vertebrae but be cautious as many unnecessary back surgeries are done every year. Get a second opinion and try other avenues first unless it’s a sure thing. Common non-surgical methods include injections of anti-inflammatories, physical therapy, chiropractors, acupuncture and bed rest. Most bulging and herniated disc treatments will focus on creating space and reducing pressure on the disc to allow it to reabsorb and repair itself.


Therapeutic massage can play a role by helping to create the space needed for repair while allowing the postural muscles to continue to support the back. Because symptoms may cause limping, unusual postures or other compensations massage can be very useful in managing pain and dysfunction in muscles being overused and misused as well as keeping muscles directly served by the nerve healthy and pain free while the impingement is being treated.


· Piriformis Syndrome

Beneath your large gluteus maximus muscle is a small triangular muscle running from the outside border of the sacrum to the top of your femur. This is the piriformis muscle and the sciatic nerve runs beneath, or in a small percentage of the population, through it. Spasm of the muscle may cause it to press on the nerve.


There are a number of common activities that can cause piriformis syndrome:


o Lots of sitting.

o Sports such as running and cycling.

o Flat feet or other problems that lead to overpronation of the foot.

o Wallets carried in back pockets.


In addition to the nerve impingement symptoms of numbness, tingling, pain, and muscle weakness a short, tight piriformis can cause the legs to rotate outward. If you notice your feet tend to turn outwards or if rotating your leg in that direction relieves the symptoms above you may have piriformis syndrome.


Massage is valuable in treating piriformis syndrome. By using the proper techniques a skilled therapist can release the spasmed muscle and relieve the compression on the sciatic nerve. Stretching and strengthening exercises can help balance the body so the piriformis is being used properly and not overworked or shortened. If your piriformis syndrome is due to a specific activity you may have to stop that activity for a bit to allow the muscle to release and recover then find strategies to prevent further injury to the muscle.


Trigger Points:

Trigger points are small knots in muscles that send pain to other areas of the body. Tension and trigger points in areas of the back, buttocks, and legs can cause symptoms similar to that of sciatica or piriformis syndrome. Assessment by a knowledgeable therapist can help determine if these muscles are the culprit.


Trigger points in the gluteal muscles of the hips are excellent mimics of sciatica as they tend to refer pain into the low back, buttocks, back of the thigh, and the leg. This pain is similar to many of the symptoms of an impinged sciatic nerve without the nerve actually being pinched. Other symptoms of these trigger points include pain on walking, getting up from a chair, and crossing your legs.


Much like piriformis syndrome the gluteal muscles can be irritated by too much sitting, standing, or walking (you can’t win sometimes!), running, limping, favoring one leg, or carrying a wallet in your back pocket.


Trigger points can form in the piriformis too but it's pattern is more local. However, a piriformis with trigger points will be tight and may cause piriformis syndrome. Here, the symptom picture is a bit more complicated including the pain referral from the trigger points as well as symptoms of sciatica.

Skilled therapeutic massage is an excellent treatment for trigger points. Figuring out the cause of extra strain on the muscle, correcting behavior along with stretching and strengthening, and learning how to treat the trigger points at home can help keep them at bay.


If you’re having pain in your backside, don’t jump to the conclusion that you have a bulging disc. Check with your doctor and your massage therapist. It may be a muscular issue that can be resolved with a few massages along with some stretching and strengthening. That is much more pleasant than getting injections of tissue-damaging cortisone or expensive and risky back surgery. If you discover there is indeed a herniation a skilled therapist can help you manage compensation problems that may arise without causing further irritation to the disc.
