What is Sciatica?
The term refers to pain that travels down the back of your leg from the lower back or buttock as far as the foot. This is caused by irritation of the sciatic nerve and is often accompanied with back pain but more often the leg pain is worse than the back.
Nerves leave the spine through small tunnels made by the bones of the spine. Some of the nerves in the lower back merge to form the sciatic nerve which runs down each leg. This happens on both sides of the spine so you may suffer sciatica in either leg. If the nerves are irritated where it travels through the tunnel due to a swollen joint, muscles or ligaments or a bulging disc, in some cases pain can occur anywhere along the length of the sciatic nerve.
Why does the pain travel down the leg?
This is because of the nerve irritation described above. The irritation leads to severe shooting pains traveling down all or part of the sciatic nerve along its path in the leg; this may be accompanied by pins and needles and/or numbness. The sciatic nerves send messages to the brain about the irritation and makes the brain think there is a problem with the nerve itself and not in the back which is the cause of the pain.
What should you do?
As with other back or neck related pains the key is to keep active but you may need pain killers to achieve this, and you cannot do yourself any harm in doing so. Following either a GP consultation or appointment with PhysioHey you will be given advice and exercises. Advice will relate to keeping active which will stop your muscles becoming tight and weak, which may cause problems in the longer term. You will experience some pain and discomfort during your recovery but this is not harmful.
Are there signs or symptoms to be concerned about?
Sciatica is rarely a sign of a serious problem, but is unpleasant when you are suffering this form of pain. The pain experienced does not mean more damage is occurring. Many cases of sciatica resolve without specialist input when given good advice and most others resolve within 4 weeks.
However if you experience the following you should seek urgent help;
- Being unable to pass urine when you feel the need to go
- Lose control of your bowels
- Go numb around your bottom/groin
- Unable to get an erection
- Have pain in both legs and/or worsening weakness in the legs
If you are unable to discuss the above symptoms with your PhysioHey clinician or a doctor you should attend your nearest Emergency Department for urgent assessment.

MSDs are a main cause of people being off sick from work. Physiotherapy is extremely effective with MSDs. In one study, 80 per cent of people who had physiotherapy for their MSD were able to carry on working and did not have to go off sick. Back pain has a wide variety of causes, from picking up a heavy parcel incorrectly to spending too long in one position. Feeling very anxious or stressed can make your pain worse.
