Almost everyone has suffered physical pain at some point in their lives. Pain is multi causal - in cases of acute traumas (wound or injury), there is a soft tissue injury comprising swelling, haematoma, pain and reduced mobility. Sporting injuries and domestic accidents usually involve damage to muscles and joint ligaments. Pain may also arise as a result of damage caused by surgery, and in later life pain due to musculoskeletal wear and tear is very common.

Chronic pain can last for months or years. In a recent U.S. study the prevalence of chronic pain was analysed after reviewing 300 patients. The study reviewed that 50% of patients suffered from at least one type of chronic pain. Pharmacy records showed that 75% of patients with chronic pain were prescribed at least one painkiller, and most received two or more. More amazingly, 44% of those patients received a dependance causing type of pain relief.

Many patients no longer want to suffer the unwanted side effects of pain killers and try to find alternatives to the traditional methods of easing pain.

One such option is low level laser therapy. Laser is a focused light with various wavelengths. High intensity laser generates heat and is usually used in surgery, but low intensity lasers are safe, and have a positive effect on bodily tissues. They neither generate heat nor scorch, and use only light, which makes them a fast, safe and precise healing measure, with no risk or after effects, and no need for surgery, anaesthetics or drugs. Laser can strengthen damages cells. Using photochemical processes, laser light inserts bio photons into damaged cells. The cells begin to produce energy (ATP), which improves their function, assists their division, strengthens the body's immune system, and causes the secretion of various hormones. The tissues are healed, and pain disappears. If damaged cells have died, the bio photons help the division of neighbouring cells, generating new tissues, and thus bring about healing.
