Sciatica happens when the sciatic nerve — which runs from the lower back down each leg — is irritated or compressed, for example by a bulging disc or tight muscles. It usually affects one side.
Sciatica often gets better on its own within 4 to 6 weeks, although it can last longer. Keeping active and doing gentle exercises usually helps.
Physiotherapists, osteopaths and chiropractors can assess the cause and use treatment and targeted exercises to ease pressure on the nerve and improve mobility. Massage and soft tissue therapy can relax tight muscles in the lower back and buttock (such as the piriformis) that may be contributing.
