Where the sciatic nerve is located in the body
The sciatic nerve, also known in the profession as nervus ischiadicus, is the longest and thickest nerve in the human body. It originates in the spinal cord and extends over the buttocks and legs down to the feet.
Why the sciatic nerve can be painful
This is therefore a nerve pain, also known as sciatica or sciatic pain.
The causes can be:
- A slipped disc pressing on the sciatic nerve which is a common occurrence.
- A particularly tense piriformis muscle in the buttocks.
- Narrowing of the spinal canal.
- Inflamed nerves or other inflammatory processes.
- A tumour in the spine, although this is seldom the case.
Typical sciatica symptoms
- Pain that extends from the lower back through the buttocks to the leg, even as far as the toes. Usually only one leg is affected.
- Pain that increases under strain, for example when lifting a heavy object, and sometimes when coughing, sneezing or pressing.
- Pain that is accompanied by sensory disturbances such as tingling, burning or numbness, or signs of paralysis in individual muscle groups in the leg.
What is important with sciatica treatment
If the sciatica is severe and lasts for a longer period, a medical check is advisable. At the examination, the doctor will check the patient’s level of mobility and sensory responses. Methods for this include the Lasègue test: while the patient is lying, the doctor slowly lifts the stretched leg. With a damaged sciatic nerve, this movement will cause the patient to experience typical symptoms when the leg reaches an angle of around 45 degrees.
Immediate help for sciatic pain
Emergency treatment is used to relieve the pain as quickly as possible and restore normal mobility. Anti-inflammatory and pain-relieving drugs are used for this purpose, which – depending on the severity of the symptoms – may also be injected. In addition, warm compresses or massages can help.
Which sciatica exercises are useful
Generally the pain fully disappears: at the quickest after a few days, at the longest after a few weeks. Once the painful phase has passed, active prevention is important in order to lower the risk of recurrence. For this, it’s a good idea to take a back training course. Physiotherapists can teach you how to exert as little strain as possible on your back when lifting objects and to avoid incorrect posture when sitting.
This exercise stretches the muscle group that often tenses up with sciatic pain: the gluteal muscles.
- In a lying position, bend the right leg.
- Bend the left leg and place it on the right knee. The left ankle joint lies on the right knee.
- If you feel a stretch in this position, maintain the pose as it is.
To further increase the stretch intensity, press lightly against the left knee with your left hand.
This exercise will enable you to massage any muscle tension in your buttocks yourself.
- Lie on the floor.
- Place a ball (such as a tennis or fascia ball) under the upper half of the buttocks.
- Place some of your weight on the ball and slowly roll the ball along the buttocks.
- Massage each painful point with small rolling movements.
It's therefore important to observe the following points:
- Ensure that any pain remains at a tolerable level.
- Discontinue the massage if you feel a strong, stabbing pain.
- Massage only briefly to start with, and with little pressure. After a time, you'll develop a feel for how much pressure is good for you.
