Definition and anatomy
Le sciatic nerve is a mixed nerve. They are composed of both motor fibers (responsible for the flexion of the knee and ankle) and sensory fibers (responsible for the sensations of the postero-external part of the leg and the whole of the foot).
Le sciatic nerve is the longest and most voluminous nerve in the body.
On each side of the lower limbs, the sciatic nerve roots originate in the lower back. Once the plexus is formed, it then moves through the pelvis, buttock, to reach the thigh.
Arrived at the interior of the thigh, the nerve descends vertically, along the semitendinosus muscle to reach the knee. This is where it branches into two main branches: the tibial nerve and the common peroneal nerve. The first innervates the posterior part of the leg, the ankle and the sole of the foot. As for the second, it innervates the back of the foot.
The term " sciatica is commonly used to describe any pain, motor disturbances, and sensory disturbances that appear on the path areas of the sciatic nerve.
Symptoms can be felt anywhere along the path of the sciatic nerve: in the lower back, in the hip, in the buttock, down the leg, in the foot and even up to the toes.

Numb toes and foot pain: what is the link with sciatica?

The latter can be felt at the heel and on the front. It can manifest itself in an isolated way or, in certain cases, be associated with a calf pain, in the thigh and in the lumbar region.

Omega-3s : Omega-3 are polyunsaturated fatty acids that play a very important role in the functioning of our body. They are provided by food in three natural forms: docosahexaenoic acid (DHA), alpha linolenic acid (ALA) and eicosapentaenoic acid (EPA). Beyond their action on the brain and the cardiovascular system, omega-3s prove very effective against inflammation. Indeed, they have the ability to act on the inflammatory mechanisms in osteoarthritis by slowing down cartilage destruction, thus they reduce the intensity of osteoarthritis pain. Since sciatica is most often linked to inflammation secondary to a herniated disc, it can also respond to omega-3s if you consume them regularly.
Lemon eucalyptus: Eucalyptus is a plant most often used in the form of herbal tea or essential oil. She would have anti-inflammatory effects which give it the ability to act on the bone and joint pain in general and the pain of sciatica in particular.
