There are people all over the planet who suffer from sciatic nerve damage. Sciatica is actually a group of related symptoms which involved pain and irritation of the sciatic nerve roots, or even the actual nerve itself. A person who is suffering from sciatica will feel pain in their lower back. These pains can also be felt in other areas such as the buttock and even the legs. Pain is not the only symptom of sciatica. You will also feel some kind of weak feeling in your muscles and perhaps numbness through the areas associated with sciatica. This can be identified as a feeling of "pins and needles" in your hips, legs, feet, buttock and lower back. This can result in a person who is affected by sciatica having trouble with their movement. Your mobility might be limited.
When you are looking to treat sciatica you should realize that the problem is more of a set of different symptoms rather than the cause of the problem. This is why many people have different opinions on whether sciatica is actually a condition, or rather a set of different symptoms. The pain that you feel in your lower back and other symptom areas might be caused by something which is different from other sufferers. The cause might be different in different cases.
Sciatica is caused by nerves being pressed against by other parts of your body. They become tight and compressed. Sciatica can be caused by a spinal disc herniation that pushes up against a nerve of the sciatic root nerve. A disc can become herniated when liquid which is inside of the disc starts to be pushed out. This can cause many problems which will lead to sciatica.
Sciatica can be caused when you activate a trigger point that is located on your lower back.
