A demurrer is of two kinds; general or special. With respect to the effect of a demurrer, it is a rule that a demurrer admits all such matters of fact as are sufficiently pleaded. Again, it is a rule that on a demurrer, the court will consider the whole record and give judgment for the party who, on the whole, appears to be entitled to it.
Thighs hurt only when sitting. When I sit, the back of my legs (both)ache. It hurts between the back of the knee up to the butt (the thigh muscle). But more just above the back of the knee. Also more when I sit on a soft couch or chair, opposed to a hard chair. When I stand, walk or run, even for miles.
It can be worse when you cough or sneeze, and prolonged sitting can aggravate symptoms. Usually only one side of your body is affected. Some people also have numbness, tingling or muscle weakness in the affected leg or foot. You might have pain in one part of your leg and numbness in another part.
