The sick person may even exhibit symptoms which have not been manifested for months or even years. The time element in the healing process is always questioned. If a disease has been in progress for a number of years and has reached a maximum degree of abnormality, recovery cannot be expected in a. few days. Acute diseases respond rapidly, while chronic cases of long standing, are slower in response. Do not get discouraged, because good health can be achieved.
Some abnormalities show an extensive involvement of tissue, while others show very little.
In some diseases, scientists have never determined what tissues are. involved or in what way they are altered. When a sick person is suffering from a disease, there is an abnormality in the function of the tissue. This can be seen by various skin eruptions, where the tissue gradually becomes abnormal. The skin returns through the steps it has covered in its appearance, until it becomes normal. This is true of tissues, in the body, which are not visible and for abnormally contracted muscles.
