Sciatica can also be caused by pressure on the nerve due to a herniated or bulging disc.
A disc herniation is when a disc protrudes outwards from between two vertebrae. This can be due to a trauma such as a road traffic accident or simply months or years of uneven pressure due to muscular imbalances.
The above is an example of a herniated disc. You can see the fluid within the disc protruding out and pressing on the nerve. This is the type of damage muscle and soft tissue imbalances can create when they are not addressed.
Unfortunately ultrasound, electrical stimulation, medications, cortisone injections, general exercises or chiropractic adjustments have not proved to be viable long term solutions.
Herniated discs are probably one of the most common diagnosis for sciatica and this diagnosis is often used when a doctor can’t find an explanation for a person’s pain..similar to a doctor explaining away various aches and pains as arthritis or wear and tear.
The problem is, many people who are diagnosed with a herniated disc don’t have pain because of it. For years research has shown that in many cases people live with herniated discs yet never have any back pain or symptoms. The point is, if you have been diagnosed with a herniated or bulging disc, it may not be what’s really causing your back pain! Even if you have had x-rays and MRI’s done that show a herniated disc, chances are still very good that it’s not the problem – the primary cause or factor in disc herniation is muscle imbalances.
