A cyst is a fluid [or pus] filled sack that is round, has a well-defined edge to it. It can be red, sore & hot [when infected], and develop a 'head' [like a boil]. There are sebaceous cysts along the hairline in the back of the head and neck, in the arm-pit and upper chest/back areas as well as in the pubic areas. They contain dead skin cells and oil from the oil gland [in which they originate]... The oil & skin cells are professionally referred to as'desquamated epithelium and sebum [hense, 'sebaceous' cyst]... A muscle spasm [knot] is rarely round... and is more eliptical --or long-- in shape. Is never hot or fluid-filled and has a poorly defined edge [border] to it. It is usually 'sore' to palpation [when pushed on] and when you are relaxed it can usually be moved side-to-side, and becomes less-so when you tighten the muscles in the area... Also the soreness increases when the muscles in the same area are tightened...
It depends on your definition of knot. There are often large deposits of fatty tissue called sebaceous cysts which are benign and harmless and can often last for years, sometimes lifetimes. the main difference between a "knot" and a "cyst" would be that a knot suggests it came about as a result of an injury. If you are concerned, check with a dermatologist...
