HOW TOPICAL ANALGESICS WORK

Muscle pain is the build-up of lactic acid that causes the soreness and pain and can occur in many ways:

1. Repetitive Strain Injuries:
Repetitive Strain Injuries, frequently associated with painful muscles, is a very common and painful musculoskeletal disorder that currently affects more than 2.5 million Canadians (usually between 30-50 years old) and growing in sufferers each year.


2. Sports Muscle Strains and Pains:
Sports and strenuous physical activities such as gardening, snow shoveling and heavy lifting put enormous pressure on older joints and muscles, resulting in soft tissue injuries and muscle pain.

Muscle pain from sports and physical activities is on the increase. One reason is that aging baby boomers refuse to give up the pursuits they enjoyed as teenagers and young adults.

Another reason is that Canadians are simply more physically active; with Statistics Canada reporting that 50% of the population was physically active in 2003, compared with 25% in 1981.

3. Arthritic Pain:
If you suffer from arthritis or think that you are starting to develop it, you are not alone. More than 4 million Canadians suffer from some form of arthritis and this number will grow as the current population ages.

There are actually more than 100 different kinds of arthritis, with inflammation affecting the joints, soft tissues and tendons. Symptoms of arthritis include pain, swelling, stiffness, redness and loss of motion.

The most common forms of arthritis are rheumatoid arthritis and osteoarthritis. Rheumatoid arthritis often strikes people in their mid-twenties and occurs more often in women.

It is believed to be caused by a problem in the body's immune system and can cause inflammation in joints, leading to cartilage and bone loss, even deformity.

Osteoarthritis is a slow breakdown of cartilage in the joints, resulting in bone rubbing against bone. The commonly affected joints are the ankles, elbows, knees, hips, hands, or back. It is more common in older people.

Arthritis can be very painful at times, but there are ways to cope with it. If you suspect that you are developing arthritis, you should see your physician. Arthritis is more manageable if you stay active, lose weight to reduce the stress on joints, eat properly and get plenty of rest

4. Solution to Pain:
You don't have to suffer through muscle pain. Topical analgesics such as RUB·A535® can relieve muscle pain by means of a counterirritant action.

Here's how it works: Counterirritants work by pitting one type of sensation against another, which causes the body to lower its sensitivity. When applied to a painful joint or muscle, counterirritants produce a temporary local reaction - a sensation of coolness or heat - that results in a lessening of pain.

Most counterirritants use heat or cold to "distract" the brain from recognizing the original pain source. Your brain's pain centre is overwhelmed by the different nerve signals it is receiving and temporarily ˜switches' the signals off, providing pain relief.
