As stated above, the main cause of a Wrist Drop is overuse of the wrist whether it be with occupation or sports. Wrist drop may also be caused due to a trauma to the radial nerve by way of a cut or stab wound, or if a person suffers a gunshot wound to the wrist affecting directly the radial nerve. Another cause for a Wrist Drop is some sort of injury to the joint in the wrist or elbow resulting in persistent swelling of the elbow.
A. It's not a great idea. Cream tends to separate when frozen, and while you can freeze a carton of cream (double-wrapping in freezer bags is recommended), you can also shake it thoroughly after it thaws to reblend it (although it will not be as good as new).
Such a deal! It's a chain reaction of freezing-point depression. The freezing point of cream is depressed by the milk and sugar particles, and the freezing point of the water is depressed by the particles of salt.
