Causes:
Sprains are joint injuries caused by enormous stretching of the joint beyond its normal range of movement, by twisting or distorting it, for example. Doctors also use the word to refer to the hyperextension or straining of muscle, ligaments and tendons surrounding the joint.
Symptoms:
Cramp-like pain, possibly followed later by swelling of the joints in question.
First Aid:
Raise the injured limb (the leg, for example), apply an elastic bandage and cool. Ideally, press cool packs (which are frozen in the freezer compartment of the fridge) against the place requiring treatment. Repeat the cooling process several times.
Later, place an ointment dressing on the injury. Apply to painful area an ointment such as Traumeel in a layer as thick as the back of a knife, put a compress on it and enclose the entire area in a tight fitting elastic bandage.
