Sciatica is another of the more common forms of neuralgia.
It is of undoubted value as a local anodyne in sciatica and neuralgia, especially in ordinary facial or trigeminal neuralgia.
Attacks of sciatica are often attended with great suffering, and are apt to be very intractable to treatment.
The plan at one time resorted to of dividing or excising a portion of the affected nerve is now seldom employed, but the operation of nerve-stretching in some forms of neuralgia, notably sciatica, is sometimes successful.
In pain due to violent sciatica relief and even permanent cure has been obtained by the injection of morphine directly into the muscle of the affected part, and in the treatment of renal and hepatic colic morphine given subcutaneously will relieve the acute pain consequent on the passage of biliary and urinary calculi.
