This is also sometimes known as weed, Monday morning fever, etc. It occurs oftenest among heavy work horses that are working hard and being fed highly. They are sometimes allowed to stand in the stable idle for a day or two and the full amount of feed given; a larger amount of nutritive material is formed than can be taken up by the absorbents and the result is an attack of the disease.
Symptoms. - After a day or two of complete idleness the horse will be found with one hind leg badly swollen and very tender to pressure, especially along the line of the lymphatics on the inside of the leg. It may occur in both hind legs, and it is possible, in the fore legs. The appetite is generally gone, the pulse very full, and the horse shows signs of suffering.
Treatment. - Give a dose of aloes according to the size and strength of the horse; and give half-ounce doses of nitrate of potash three times a day. Bathe the swelled leg with very warm water for half an hour, then rub on a liniment made of tincture of arnica, fluid extract of lobelia and distilled extract of witch hazel, equal parts. As soon as the inflammation passes off the horse should be turned out for exercise.
