Sciatica is a condition that occurs when something presses or rubs against the sciatic nerve, which runs from the lower back down the back of the leg into the foot. It can cause a range of symptoms, including pain, tingling, numbness, and weakness in the legs and feet. While sciatica usually affects the bottom and the back of one leg, it can also cause numbness in the genital or anal area, known as Cauda equina syndrome, which requires immediate medical attention. The condition can be caused by a herniated disc, degenerative disc disease, spinal stenosis, or spondylolisthesis, and is more common with age.

Sciatica is caused by a herniated disc, degenerative disc disease, or spondylolisthesis
Sciatica is a painful condition that affects the back, buttocks, and legs. It can be caused by any condition that affects the sciatic nerve, which is the longest nerve in the human body. The sciatic nerve runs from the L4-L5 vertebral junction into the buttocks and down the outer length of the leg into the foot.
Sciatica can be caused by a herniated disc, which is also referred to as a ruptured disc, bulging disc, protruding disc, or a pinched nerve. It occurs when the gel-like interior of the spinal discs leaks and irritates the nerve. Herniation can also happen when the disc becomes compressed from disc degeneration, causing the inner core of the disc to bulge out and press against the nerve. This compression can cause pain that radiates from the root of the nerve down into the foot. The lumbar (lower back) and cervical (neck) regions are most susceptible to herniated discs because they experience the most movement and wear and tear.
Degenerative disc disease is another cause of sciatica. It is a result of the wear and tear of the spinal discs over time, which can lead to pinched nerves. While it is not an inevitable part of aging, degenerative disc disease can be accelerated by age-related conditions like osteoarthritis.
Spondylolisthesis can also cause sciatica. This occurs when one vertebra slips forward onto the one below it, causing the collapse of the disc space and fracture of the connecting bone. This can put pressure on the sciatic nerve, leading to sciatica symptoms.
The symptoms of sciatica include pain, numbness, and weakness in the legs, which can interfere with activities such as walking, running, and lifting the leg. It is important to note that the symptoms of sciatica may vary between individuals.

It can cause numbness, tingling, and weakness in the legs
Sciatica is characterised by pain that starts in the buttock and radiates down the back of the leg, often including the foot and toes. It is caused by something pressing or rubbing on the sciatic nerve, which comes from nerve roots in the lower spine. This pressure can be the result of a herniated disc, the most common cause of sciatica, or degenerative disc disease, both of which are more likely to occur as a person ages. Other causes include spinal stenosis, spondylolisthesis, and isthmic spondylolisthesis.
Sciatica can cause a range of symptoms, including pain, tingling, numbness, and weakness in the legs. The specific symptoms and their severity can vary, and they may be constant or have sudden flare-ups due to certain events, such as lifting heavy objects or bending down for extended periods. For example, some people experience a pins and needles sensation on the outer side of the calf, extending to the web space of the first toe. Others may feel burning pain along the back of the thigh and calf, causing stiffness in the leg.
One of the most common symptoms of sciatica is leg weakness, which can manifest as a pulling sensation in the leg and affect movements such as walking, running, lifting the leg, or flexing the foot. This leg weakness is due to interference in signal communication between the brain and leg muscles caused by spinal nerve root issues. In addition to leg weakness, sciatica can also cause numbness in the toes and back of the thigh, which may be relieved by standing up.
While sciatica usually improves with time, it is important to seek medical care if you experience sudden lower back pain, especially if you have a history of cancer, an autoimmune condition, or unintended weight loss. Additionally, if you have problems controlling your bladder or bowels or experience numbness in your genital or anal area, seek immediate medical attention.

Symptoms include pain, pins and needles, and muscle spasms
Sciatica is a condition that occurs when something presses or rubs on the sciatic nerve, which runs from the lower back, through the hip and buttock, and down the back of the leg to the foot. Sciatica is often caused by a herniated disc, but can also be caused by degenerative disc disease, spinal stenosis, or spondylolisthesis.
The symptoms of sciatica can vary, but often include pain, pins and needles, and muscle spasms. Pain associated with sciatica can range from a dull ache to searing pain, and may be worse when moving, sneezing, or coughing. It is also common to experience leg weakness, which can manifest as a pulling sensation in the leg and can affect activities such as walking, running, and lifting the leg.
Pins and needles associated with sciatica can be felt on the outer side of the calf, extending to the web space of the first toe. This can occur in conjunction with leg weakness when walking on the toes or heels. Numbness is another common symptom of sciatica, which can be felt in the toes or back of the thigh, and may be accompanied by a tingling sensation.
In addition to these symptoms, sciatica can also cause burning pain along the back of the thigh and calf, stiffness in the leg, and electric shock-like pain along the back of the thigh and leg. These symptoms may be constant or may flare up due to certain activities or movements. While sciatica usually improves within a few weeks to months, it is important to seek medical advice if symptoms persist or worsen.

Treatment options include painkillers, physical therapy, and surgery
Sciatica can cause a range of sensations, from mild aches and sharp, burning sensations to extreme discomfort and numbness in the leg muscles. Treatment options for sciatica include painkillers, physical therapy, and surgery.
Painkillers
Over-the-counter painkillers such as acetaminophen, aspirin, or NSAIDs (ibuprofen, ketoprofen, or naproxen) can be used to manage sciatic pain. Prescription muscle relaxants can also be used to ease muscle spasms.
Physical Therapy
Physical therapy can help reduce or eliminate sciatic nerve pain. A physical therapist will help determine the specific cause of the pain and design a treatment plan. This may include stretches, nerve glides, and manual therapy to reduce tension and improve nerve mobility. A typical physical therapy session will involve 6-8 exercises, which can include therapeutic band exercises, light bodyweight exercises, or exercises with minimal weights.
Surgery
Surgery is a last resort for treating sciatica and is only recommended if other treatments have not been effective. The goal of surgery is to remedy the cause of sciatica, such as correcting a herniated disc that is putting pressure on the nerve. While surgery can result in significant pain improvement, it does not guarantee that numbness will be resolved, and there is a chance of sciatica returning.

It is important to seek medical care if symptoms worsen or persist
Sciatica is a common cause of back and leg pain. It is caused by inflammation or injury to the sciatic nerve, which runs from the lower back, down the back of the legs, and into the feet. Common symptoms include pain, weakness, or numbness in the lower back, buttock, leg, or foot. While sciatica usually gets better in a few weeks to a few months, it is important to seek medical care if symptoms worsen or persist.
If you experience sciatica symptoms, it is recommended to rest and decrease your activity to minimise irritation of the sciatic nerve and allow the area to heal. However, bed rest is not recommended, as it is beneficial to get up and move around gently. You should also avoid any movements that lead to increased pain and consider gentle stretching exercises for the lower back to help relieve nerve compression.
While self-care can be effective in managing sciatica, it is important to seek medical care if your symptoms persist or worsen. If you continue to have pain and problems with movement after a few days of self-care, or if your condition deteriorates, you should consult a doctor for sciatica treatment. Family doctors, general practitioners, chiropractors, and physical therapists can diagnose and treat simple cases of sciatica.
In some cases, sciatica symptoms may indicate a serious medical condition. Atypical symptoms, such as numbness or weakness in the legs, or bowel or bladder dysfunction, are red flags that should be evaluated by a medical professional. These symptoms could indicate conditions such as spinal cord compression, infection, or cauda equina syndrome, which require prompt medical or surgical intervention. Therefore, it is important to seek immediate medical attention if you experience any of these atypical symptoms.
Additionally, if you have tried various treatments and your symptoms are not improving, it may be necessary to consult a neurologist or a physician who specialises in the nervous system to manage severe sciatica. They can provide non-operative treatments such as epidurals or joint-based injections, depending on the specific symptoms. Surgery is generally considered the last option when other treatments have been exhausted.
