Sacro-iliac Joint Pain
The sacro-iliac (say: sey-kroh-IL-ee-ak) joint can be one of the causes of mechanical low back pain. It is often seen with other causes of low back pain. The sacro-iliac joint lies between the sacrum and the iliac crests of the pelvic bones. The sacrum is the bone at the bottom of your spine just above the tailbone.

Shingles and Post-herpetic Neuralgia
Shingles (say: SHING-uhlz) (or herpes zoster infection) is a painful condition that affects certain areas of the skin. It follows a chicken pox (or varicella zoster) infection — the kind that usually happens in childhood.

Spinal Stenosis
Spinal stenosis (say: sti-NOH-sis) is a narrowing of areas in the spine that causes irritation of the spinal cord or the nerve roots as they leave the spinal cord. This is most common after the age of 50, but can happen in younger people if they are born with abnormalities in the spine or if they suffer injuries to the spine.

Stroke
A stroke happens when the blood supply to the brain is cut off. Stroke can also happen when a blood vessel bursts and causes bleeding in the brain. In either case, brain cells are damaged. This can cause muscle weakness, trouble speaking, vision problems, headache, and dizziness.

Systemic lupus erythematosus (Lupus or SLE)
Systemic lupus erythematosus (SLE) is an auto-immune disease. This means that there is a problem with the body’s immune system. The immune system is designed to protect the body from threats by responding to infections, tumours, or injuries. In auto-immune diseases, the body cannot tell the difference between what is threatening and what is normal, so it attacks normal parts of the body. There are many different kinds of auto-immune diseases, and SLE is only one of them.
