HEY BRO,
Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic.

example, as i said they are non specific so eg: headache can be due to many reasons and can be related to the body but high or low blood pressure is mostly due to heart problem
