There is a modification of this treatment which suits more weakly persons, and suits also those who must do all, or almost all, for themselves. A long flannel or flannelette nightdress is used in this, instead of the blanket. This is covered on the whole of the inner side with well-made soap lather. When so covered it is put on at bedtime, and a dry nightdress put on over it. Both are then fastened as closely as possible to the skin, and the patient goes to sleep thus clothed. If the night is cold, the greatest care must be taken to be well covered, and brought to as good a heat as possible. In the morning a very great change will have come from this treatment. When the whole body is washed down with warm water, dried, and nicely rubbed with fresh oil, the skin is found very considerably changed, and in case of asthma the breathing relieved. If cold is taken when this process is fairly gone through, it would be very astonishing indeed; but if it is badly done, a person might get chilled instead of comforted. Therefore every care must be taken to keep the patient thoroughly warm. The result of one effectual pack is usually sufficient to convince the poor sufferer that he is being treated in the right way. The effect of the second is greater, and so on to the fourth or fifth, beyond which he need not go as a rule. He will do well once a day to wash with hot vinegar and rub after with the oil. These should not be required more than a fortnight at most. If chilliness continues, it is well to put on cotton stockings on going to bed, and even to bathe the feet and oil them before doing so. This bathing may be continued every night for a fortnight. Sores.--These will be found dealt with under many headings throughout this book (_see_ Abscess; Bone, Diseased; Blood; Boils; Breast; Cancer; Carbuncle; Cauliflower Growth; Eruptions; Erysipelas, etc.), therefore we here only treat generally of two kinds of common sores. The first is the surface sore, which eats inwards; the second, the deep-seated sore, which eats outwards. The first usually begins as a small pimple like a pin's head, and, if neglected, breaks, and gradually increases in size. Its origin is something which has caused the minute vessels of the skin at the spot to give way, so that they remain congested with bad blood, which soon becomes practically poisonous, and so the sore enlarges and eats into the surrounding tissue. If such a sore appears on the leg, it is often due to over-pressure through too much standing. Rest, with the leg kept horizontal or inclined slightly upwards to the foot, will often be enough to cure. When complete rest cannot be had, a thigh bandage (_see_ Veins, Swollen) should be worn.
