Liquid Propane Gas, or LPG, is a clean burning and widely available fuel. It has been listed as a clean fuel in the Clean Air Act in addition to the National Energy Policy Act. Propane is actually a byproduct of the processing of Natural Gas. It contains more carbon than NG, and therefore burns up to three times hotter. Keep in mind, however, that BTU ratings can be used to compare heat ratings between systems regardless of fuel type used.
Causes of Neuralgia. The underlying cause of any type of neuralgia is damage to a nerve. Each nerve in your body is protected by a coating called the myelin sheath. When the myelin is damaged or wears away from the nerve, the stabbing, severe, shock-like pain of neuralgia results.There are many different factors, including old age, which can cause damage to the myelin. Unfortunately, in many cases of neuralgia, a cause can never be found.he myelin on nerves can be worn away by pressure. The pressure may come from a bone, ligament, blood vessel, or a tumor that is pressing on the nerve. The pressure of a swollen blood vessel is a common cause in trigeminal neuralgia.
Postherpetic neuralgia (PHN) is nerve pain which occurs due to damage to a peripheral nerve caused by the reactivation of the varicella zoster virus (herpes zoster also known as shingles). Typically, the nerve pain (neuralgia) is confined to an area of skin innervated by a single sensory nerve, which is known as a dermatome.
