Pain is variously interpreted, according to its place and character. It may be
Acute, sharp, cutting, as in pleurisy; shooting, darting, as in neuralgia; piercing (lancinating), in cancer; gnawing, tearing, in rheumatism; dull, heavy, aching, as in pneumonia ; griping, twisting, in dysentery ; bearing down, in second stage of labor ; pulsating, in the formation of an abscess ; burning, smarting, in erysipelas; stinging, nettling, in urticaria (nettle-rash) ; constant, or intermittent; fixed or wandering.
Tenderness on pressure is generally a sign of inflammation, although some neuralgic cases have it; possibly from inflammation of the sheaths of the nerves. Tired muscles also are often sore to the touch as well as on motion.
Sometimes pain is relieved by pressure; this is often the case with colic. In such instances we conclude that there is no inflammation.
Pain is not always at the place of disease. In disease of the hip-joint, the principal pain is at the knee ; in dyspepsia, often, over the middle of the breast; when the liver is disordered, under the right shoulder-blade ; in irritation of the womb at the top of the head.
Loss of sensation (anaesthesia), occurring from disease, constitutes one kind of paralysis. The other form is loss of power to move the limbs or parts affected. When paralysis involves one side of the body only, as the right arm and leg, or the left arm and leg, we call it hemiplegia. Paraplegia is palsy of both legs at the same time.
