Symptomatic

adj. of or pertaining to symptoms; indicative, typical, representative

In medicine, a disease is symptomatic when it is at a stage when the patient is experiencing symptoms. It is generally used in counterdistinction of asymptomatic (when the disease is inapparent).Symptomatic treatment is the practice of treating a patient's symptoms, rather than the disease or injury itself.
