Pain radiating from the lower back in lower limb up to the toe is known as sciatica. In this condition, a nerve called sciatic is effected and pain occurs in the same nerve- this is the reason, why it is known as sciatica. So to be precise- pain effecting the sciatic nerve is known as Sciatica.
Common symptoms of sciatica include:sciatica-treatment
Causes of Sciatica:
Sciatic nerve originates from Lumbo-Sacral vertebrae. Nerves coming out of these vertebrae unite together and make a nerve- Sciatic. This nerve travels to the foot all the way so from lower back up to any place there might be some problem. Here are main causes of sciatica.
1. Slipped Disc:
When due to problems with the muscles of the spine, a disc bulges to a side and starts pressing the nerve root, involved with the sciatic nerve, this irritates the nerve and sensation of – pain/numbness/tingling starts occurring in the whole nerve. This kind of sciatic pain can only be relieved when the pressure on the nerve root is removed by proper adjustment of the disc.
2. Lumbar Spinal Stenosis:
This is the condition of hardening of the spinal canal- this is a condition which follows the lumbar spondyolitis ion general.
3. Degenerative Disc Disorder:
This is the condition where inter-vertebral disc starts degenerating due to some pathology and this starts effecting the nerve roots and pain starts travelling down to the leg.
4. Piriformis Syndrome:
This is a controversial cause of sciatica. When there is no definitive cause for the problem- all the discs are in their place, there is not a problem with the spine- this is considered that pain is due to the stiffness in the piriformis muscle. This might be a confusing diagnosis but certainly, in practice, we have seen many patients came with severe pain but there was nothing wrong with their spine or vertebral column.
