LUMBAGO, a term in medicine applied to a painful ailment affecting the muscles of the lower part of the back, generally regarded as of rheumatic origin. An attack of lumbago may occur alone, or be associated with rheumatism in other parts of the body at the time. It usually comes on by a seizure, often sudden, of pain in one or both sides of the small of the back, of a severe cutting or stabbing character, greatly aggravated on movement of the body, especially in attempting to rise from the recumbent posture, and also in the acts of drawing a deep breath, coughing, or sneezing. So intense is the suffering that it is apt to suggest the existence of inflammation in some of the neighbouring internal organs, such as the kidneys, bowels, <fcc., but the absence of the symptoms specially characteristic of these latter complaints, or of any great constitutional disturbance beyond the pain, renders the diagnosis a matter of no great difficulty. Lumbago seems to be brought on by exposure to cold and damp, and by the other exciting causes of rheumatism. Sometimes it follows a strain of the muscles of the loins. The attack is in general of short duration, but occasionally it continues for a long time, not in such an acute form as at first, but rather as a feeling of soreness and stiffness on movement. The treatment includes that for rheumatic affections in general (see Rheumatism) and the application of local remedies to allay the severe pain. Of these the best are hot fomentations with turpentine or laudanum applied by means of flannel or spongio-piline to the part ; or the rubbing in, if this can be borne, of stimulating liniments, such as those of opium, belladonna, chloroform, aconite, <fcc. The old and homely plan of counter-irritation by applying a heated iron to the part ...with a sheet of brown paper interposed is often beneficial in chronic cases, as is also, on similar principles, Corrigan’s button cautery. The subcutaneous injection of morphia or atropia is called for when the attack is very severe and prevents sleep.
