Sciatica - Symptoms 

Symptoms of sciatica 

Sciatica is different to general back pain; the pain of sciatica hardly affects the back at all but radiates out from the lower back, down the buttocks and into one or both of the legs, right down to the calf.

Sciatic pain can range from being mild to very painful and can last for weeks or months. If it lasts for more than six weeks, it is considered persistent (chronic) sciatica.

Other symptoms

If you have sciatica, you may also experience the following symptoms around your legs and feet:

  • numbness
  • tingling
  • muscle weakness 
  • loss of tendon reflexes

Cauda equina syndrome

Cauda equina syndrome is a rare but serious condition that can cause sciatica. The cauda equina is the bundle of nerves that lead out from the end of the spinal cord. Cauda equina syndrome occurs when these nerves are compressed and damaged.

It can eventually lead to paralysis if left untreated.

One of the warning signs of cauda equina syndrome is suddenly losing control of your bladder or bowels. If this happens, see a doctor immediately.
