It is important to understand that sciatica is not a disease but rather a symptom caused by a set of other underlying factors.
Firstly the most common cause of sciatica is a protruding disc or herniated disc which causes pressure on the sciatic nerve.
A herniated disc is caused by being displaced as well as external pressure resulting from constant pressure or an accident.
However, people that suffer from sciatica due to a herniated disc may not experience pain.
In additional Piriformis Syndrome may also cause sciatica.
This syndrome causes the Piriformis muscle to exert pressure on the nerve when a muscle imbalance causes the joint in the area of the pelvis to be displaced which results in the piriformis muscle seat changing and in turn applies pressure on the nerves in that area.
Another cause could be due to spinal stenosis which is the constriction or narrowing of the spinal space in the canal which causes muscle imbalance.
Muscle imbalance puts more pressure on the spinal area and hips and in turn causes these areas to become awkwardly positioned as well as causes irritation and inflammation due to continuous pressure and contact on the sciatic nerve.
Other causes of sciatica are Isthmic spondylolisthesis which is caused from dislocated vertebrae and in turn causes the nerve to become pinched.
However, all these causes have a common factor such as muscle imbalance or muscle strain.
Many people suffer a muscle injury during their lifetime which in turn means that the flexibility of the muscles is reduced and in which case causes pain and causes sciatica symptoms such as muscular irritation, tingling and numbness.
Such symptoms may also reflect a health condition and one should consult with a physician in order to make a positive diagnosis.
Depending on what is causing the sciatica symptoms one may require surgery.
The common treatment for sciatica is analgesics, anti-inflammatory medications and exercises that are designed for lower back pain which will bring about complete or partial relief.
Even though medications and exercises are a common treatment, these need to be taken under the supervision of a professional.
There are also several natural sciatica cures that have proven effective for sciatica pain such as home remedies and homeopathy along with stretching and lower back exercises.
In the case of severe sciatica one should follow their physician's instructions carefully or in some instances the person may have to have a surgical procedure.
