Piriformis syndrome is caused by trauma due to tight piriformis muscles. Direct blow to the buttock. It can be a gradual onset or come on suddenly.

The pain is felt in the buttock region and going down the back of the thigh, also the outside of the calf and foot. Usually pain felt is like a burning sensation, deep pain in the buttock region with lower back pain  and hip pain.

It is best to avoid any activity that aggravates the pain and seek a health professionals advice.

Disc Degeneration 

Discs of the spine are the cushions that are placed between the vertebrae to protect them from damaging each other. The degeneration of the discs causes the discs to become more susceptible to herniation and lead to localised or radiating pain. Sciatica can result from disc herniation when nerves in the lower back are irritated.

 

CAUSES

As we age the water and protein content in the discs change and become fragile and thin.

Trauma is another way that can lead to disc degeneration.
 

Avoiding injury can prevent these conditions. When it already exists, aggravation of the existing symptoms can be avoided by limiting stress or overusing the involved spine.

Diagnoisis 

Ways to be diagnosed are by having an MRI and an xray.

 
Treatment
 
It will still occur, often able to be managed conservatively. It’s all about managing it.

What is Sacroiliac Pain?
First of all where is the sacroiliac joint within the body? The sacroiliac joint is part of the lower back and joins the tail bone to one of the pelvic bones.
             It acts to transfer weight from the spine to the pelvis. Allowing for small movements to occur. If there is too much force placed on the sacroiliac joint and surrounding ligaments then an injury may occur. This is known as Sacroiliac dysfunction.

Causes of Sacroiliac Pain.
Causes of sacroiliac joint pain can be excessive forces of the muscles and ligaments in the area. It can come from bending, lifting, sitting, arching, twisting movements of the spine, even from weight bearing forces from jumping or running. Also things such as a sudden trauma or repetitive action can cause sacroiliac joint pain.

Signs and Symptoms.

• The pain is usually felt on one side of the lower back, top of buttocks, sometimes referring into the lower buttock, groin or thigh.
• Rare cases it can be felt on both sides of the lower back.
• Rolling over in bed, putting or taking off shoes, walking up and down stairs or running.
• May also be associated with asymmetry of pelvis, due to muscle tightness, joint stiffness or joint laxity associated with pregnancy.

Treatments.

• Myotherapy
• Massage
• Mobilisation
• Taping
• Dry needling
• Exercises to improve muscle strength, flexibility, posture and core stability.

Contributing Factors.

• Muscle imbalance
• Leg length
• Muscle weakness or tightness
• Biomechanical abnormalities
• Poor posture
• Lumbar stiffness
• Poor core stability
• Inappropriate lifting techniques

Disc Bulge occurs due to sudden trauma involving forward, backwards and side way movements. There is too much compression placed on the discs. There can be numbness, dizzy, thermal changes, tingling and tiredness that is associated with it.
