Head
There is a sensation of enlargement of the head which is felt as a painful congestion and fullness, especially during pregnancy. The sensation is ameliorated by wrapping the head. Congestion of the head with throbbing of the carotids and a feeling of discomfort around the throat.
Headaches may be produced by emotional excitement, but more especially from frights and also from mental exertion. The headaches frequently have a slow, gradual onset but then decrease rapidly. On the other hand, Argentum nitricum also produces a violent headache which starts very suddenly. Here again we see an amelioration from pressure; often the patient may find relief by wrapping or binding the head. Headaches, once they reach their peak, end in vomiting many times.
