4. Headache
Many people suffer from headaches, and very few relate them to illness unless there are other symptoms. A headache is often one of the first symptoms that you notice if you are sick with the parvovirus. It can go away and return throughout the entire infection. Some people even experience headaches related to the virus after it has left their system and they are no longer experiencing other symptoms.
Headaches can be managed with pain medication and plenty of rest. Often, the headache is the result of other symptoms such as dehydration or fever. Since headaches are so common and are also a symptom of many other illnesses, doctors do not consider them a telltale symptom of parvovirus. Headaches that do not go away or come back quickly once the medication wears off are usually a sign of a viral infection. Once the patient recovers, the headaches should become less frequent. Fluids can help lessen the severity of a headache too.
