First of all, for a cure, there must be _rest_. Not more than three hours at a time should be spent in an erect posture, and between each spell of three hours let one hour be spent lying down. Avoid _all_ movement while lying, as far as possible. Secondly, soap the back thoroughly with LATHER (_see_) at bedtime. Cover the well-lathered skin with a large, soft cloth, leaving the cloth and lather on all night, and covering over all with flannel in sufficient quantity to keep the patient warm. If the spasmodic twitching comes on, apply cold cloths repeatedly to the back of the neck for an hour in the morning. If this is felt too cold, apply for a shorter time. If the neck has become hard and fixed in a wrong position, rub as recommended in Muscular Action. This treatment has cured many cases. Nerve Centres, Failing.--Many diseases flow from this cause, but at present we only consider one. That is where a "numbness" begins to show itself in fingers and toes, and to creep up the limbs. No time should be lost in treating such a case. It arises from failure in the spinal nerves, and these must be nursed into renewed vitality. This will be greatly helped by wearing over the back next the skin a piece of new flannel. Rub (_see_ Massage) the back with warm olive oil night and morning, working especially up and down each side of the spine. Pursue this rubbing gently but persistently, but do not fatigue the patient, which may easily be done. Cease rubbing the moment fatigue manifests itself. Continue this treatment for weeks even, and also treat, as in next articles, _mind_ as well as body. (_See_ Locomotor Ataxia.) Nerve Pain.--_See_ Pain. Nerve Shock.--After a fright, or some very trying experience, some part of the nervous system is frequently found to have given way. Heat is felt in the stomach. Then, if no treatment is given, curious feelings come on in the back of the head. Even inflammation of the stomach and brain may come on in severe cases. In any such trouble, alcoholic drinks, blisters, opium, and all narcotics are to be strictly avoided. These only lessen the already weak nerve power. Show the patient in the first place that there is no need for anxiety, the vast majority of such cases being easily curable by right treatment. We have seen this relief of mind alone effect a perfect cure. Therefore see to giving it. Wring tightly out of cold water two ply of new flannel, large enough to go round the lower part of the body, from waist downwards to hips. Put these round the patient, with two dry ply of the same flannel above them. Wear this night and day for a week or a fortnight. Keep the feet always warm and dry. Give plain, easily digested food. If St. Vitus' Dance shows itself, treat as directed under that head. Study the case in the light of all said on nervous troubles in these pages, and you will be able to cure almost any symptoms which may arise.
