Back burning sensations are any sensations anywhere on the back that elicit a feeling of warmth or heat and may or may not be accompanied by pain. Back burning sensation may also be accompanied by a wide variety of other symptoms, some of which may include feelings of tingling or numbness (paresthesia) or itching. A host of underlying events or conditions may cause back burning sensations.
The Moonâs synodic period is the time between successive recurrences of the same phase; e.g., between full moon and full moon. The synodic period of a planet is the time required for the Earth to overtake it as both go around the Sunâor, in the case of fast-moving Mercury or Venus, for the planet in question to overtake the Earth.
So, how long does each phase of the Moon last? Well, the phases are just names we give to certain points along the Moon's smooth path around Earth. Technically, each phase, just like the one called a New Moon, when the Moon is exactly between Earth and the Sun, lasts only a brief instant. But to our eyes, a New Moon can last for a few days, representing the time that the Moon appears in the sky too near the Sun's position for us to see it at all. The time it takes the Moon to go through all its phases is about a month, and that was so important to our ancestors that they created the period of time we call a month.
