=External Piles.=--These are bluish swellings or little lumps which project from the bowel, interfering with walking or the toilet of the parts, and are sometimes exquisitely tender and painful when inflamed. In the course of time these become mere projections or fringes of flesh and cause no trouble unless through uncleanliness or other reasons they are irritated. The treatment of external piles may be summed up in great cleanliness--washing the parts after each movement of the bowels; rest in bed, if the soreness is great; the application of cold water or powdered ice in a rubber bag, or of hot poultices, and of various drugs. Among these are hamamelis extract, or witch-hazel, with which the parts may be frequently bathed; an ointment of nut-gall and opium; or extract of belladonna and glycerin, equal parts. Sitting in cold water, night and morning, in a tub also will prove serviceable. The more rapid and effectual method of cure consists in opening of the recent pile by the surgeon, or clipping off the fleshy projections. The bowels should always be kept regular in any form of piles by small doses of Glauber's or Epsom salts taken in a glass of hot water on rising, or some mineral water. In case these do not agree, extract of cascara or compound licorice powder may be taken at night. Equal parts of sulphur and cream of tartar is an old-fashioned domestic cathartic of which a teaspoonful may be taken each morning to advantage in piles. =Internal Piles.=--In the beginning patients with internal piles feel as if the bowels were not wholly emptied after a passage, and sometimes there is difficulty in urinating and also pains in the hollow of the back and in the thighs. There is often pain on movement of the bowels, and blood follows the passage. Later, blood may be lost at other times, and the loss may be so great as to cause pronounced paleness and weakness. Itching is a frequent occurrence. Mucus and pus (matter such as comes from an abscess) may also be discharged. Loss of sexual desire and power is not uncommonly present. There may be no external protrusions; but bleeding, itching, and pain during movement of the bowels are the chief symptoms. If the pain is very severe during and also after a passage, it is probable that there is also present a fissure or crack in the flesh, or ulcer at the exit of the bowel which needs surgical attention. It not infrequently happens that the piles come out during the bowel movement, when they should be thoroughly washed, greased, and pushed back. Sometimes this is impossible, although after lying down for a while and applying ice or cold water the mass may shrink so as to admit of its return. When a large mass is thus protruded and cannot be returned, and becomes nipped by the anus muscles, it undergoes inflammation and is very painful, but a cure often results from its destruction. Such a mode of cure is not a safe or desirable one, however.
