Inflammation may occur in any vein, but it is oftenest seen in the jugular vein on the side of the neck. It is the result of some injury or of a bad job of bleeding or from improper care afterward and catching cold in the wound.
Symptoms - The part becomes swollen and hot, and soon grows hard and painful. If it is the jugular vein he will hold his head out and appear as if stiff in the neck.
Treatment. - Cover the swollen part with cloths wrung out of hot water and keep it hot and steaming for several hours by pouring hot water over it; rub the part gently with the hand and aim to get the blood started. If an abscess forms open it and syringe it out with two teaspoonfuls of carbolic acid in one pint of water. If the part remains hard apply a cantharidine blister. If the vein becomes obliterated the horse cannot feed well with his head down to the ground but should always be fed from a manger afterward.
