Points douloureux, when Tender points correspond to established at a later stage, tendinous origins and insertions correspond to the emergence of of muscles. nerves. Pain not materially relieved by Pain usually completely and always any change of posture. considerably relieved by full extension of the painful muscle or muscles. The treatment of myalgia is not only satisfactory in itself, but often affords, in its results, a very desirable confirmation of diagnosis. For a very large number of cases, all that is required is (_a_) to put and keep the affected muscle in a position of full extension, which is only to be changed at somewhat rare intervals; (_b_) to cover the skin all over and round it with spongio-piline, so as to maintain a perpetual vapor-bath; (_c_) on the subsidence of the acutest pain and tenderness, to complete the treatment by one or two Turkish baths, to be taken in the manner that I have recommended by speaking of the prophylaxis of neuralgia. When treatment such as this cures a pain which was greatly aggravated by muscular movement, we may be sure that pain was myalgic and not neuralgic. The pain, however, is not unfrequently rebellious to such simple remedies as these, more especially when (as in pleurodynia) we are not able to enforce complete physiological rest of the part. When this is the case, we shall find the internal use of twenty and thirty grain doses of muriate of ammonia by far the most effective remedy. In the first very acute stage of a severe case it may be advisable to inject morphia hypodermically; but this is seldom necessary. The muriate-of-ammonia treatment may be usefully accompanied by prolonged gentle frictions, three or four times a day, with a weak chloroform liniment. When there is visibly a very great deficiency in the general nutrition, we shall often fail to obtain a cure until we have remedied this defect; and accordingly, in the majority of cases of half-starved and overworked needle-women, cobblers, tailors, and the like, who present themselves in the out-patient room, I accompany the above-named treatment with the steady administration of cod-liver oil for three or four weeks or more.
