Radiating pain caused by sciatica can be enfeebling to manage in daily tasks as it does not get better with rest. The sciatic nerve is of considerable length and the body's most extended spread out nerve. It starts from the lower back, hips and then branches out to both legs. It is the widest nerve in the body at 2cm in diameter.

The pain of sciatica is excruciating and shooting pain that travels down the leg. It is an umbrella term and symptom of underlying pathology. The pain is usually caused by a pinched nerve in the lower back or due to inflammation of the piriformis muscle surrounding the sciatic nerve.
Suffering from sciatica can affect your daily activities; simple tasks like walking, getting up from a chair or sitting down can trigger pain down the leg in an instant.
How can exercises help me ease sciatic pain?
Sciatica is a broad term and accompanies many musculoskeletal disorders under its umbrella. People tend to focus on over the counter drugs, whereas it can be easily prevented and managed by adding simple exercises to your life routine.
Exercise helps increase muscle strength, increase blood flow in all muscle fibres, enhance soft tissue health, and prevent nerve impingement. Spending 30 minutes a day or performing exercises intermittently between work can have remarkable effects on your health.
Improve and increase muscles strength; strengthening the surrounding muscles and targeting those muscle fibres that are atrophied helps reduce the load on the lumbar disc. It also helps push the discs back into their place and relieve pressure on your sciatic nerve.
Increase blood flow; increasing blood flow to dormant muscle fibres helps reduce inflammatory substances and increase the supply of nutrients in those muscles.
Improve soft tissue health; prolonged sitting in the same posture and decreased joint mobility adds more negative pressure on the discs. The pressure is targeted at one point only, which causes herniation over time. Some mobility and simple exercises can reduce the incidence and occurrence of these problems.
Prevent nerve impingement; when you adopt the same posture, some muscles have increased load compared to other muscles. As a result, they are inflamed with increased pressure. This inflammation pinches the sciatic nerve at any level in the lower limb. Physical therapy exercises reduce stiffness, inflammation and enhance flexibility in the nerve.
Release hormones; Exercise also improves mood, release happy hormones and helps clear up mind fog during work. It gives your energy to finish work on time efficiently.
8 Exercises to prevent sciatica

Summing up
Sciatica flares up when you adopt the same posture for an extended period and spend most hours in that position. Sitting for an extended period in driving a car or doing office work causes sciatic nerve impingement. It can be due to various musculoskeletal disorders, e.g. disc herniation, discitis, piriformis syndrome or inflammation in surrounding muscles.
The optimal goal of physical therapy exercises is to target the root cause of the pain. Afro mentioned exercises provide beneficial results and take a few minutes to perform. However, consult a physical therapist before performing exercises on your own.
