Introduction
Fever refers to an elevated body temperature. Headache at the back of the head following fever may be caused by autonomic nervous dysfunction, inflammatory stimulation, insufficient cerebral blood supply, or other reasons, and should be treated accordingly based on the specific condition. In addition, headache at the back of the head after fever could also result from increased intracranial pressure, which requires timely hospital visit for a thorough examination and appropriate medication based on the underlying cause.

Fever refers to an elevated body temperature. Headache at the back of the head after fever may be caused by autonomic nervous dysfunction, inflammatory stimulation, insufficient cerebral blood supply, or other reasons. Targeted treatments should be applied according to specific conditions.

1. Autonomic Nervous Dysfunction

When patients are under prolonged stress in their work environment, it can easily lead to autonomic nervous system dysfunction, resulting in orthostatic hypotension and headaches, particularly felt at the back of the head. This dysfunction can also affect the body's temperature regulation center, leading to fever. Under medical guidance, medications such as ibuprofen sustained-release capsules and oryzanol tablets may be used for treatment.

2. Inflammatory Stimulation

If the body is infected by a virus, inflammation may develop and affect the area at the back of the head. The inflammatory response can irritate local tissues, causing pain, and may also disrupt the temperature regulation center, resulting in fever. Under medical supervision, medications such as acetaminophen tablets or acyclovir tablets can be used for treatment.

3. Insufficient Cerebral Blood Supply

Fever can impair normal blood circulation, reducing adequate blood and oxygen supply to the brain. This insufficiency may trigger vascular spasms and cause pain at the back of the head. Under a doctor’s guidance, medications such as aspirin tablets or sanqi tablets may be used for treatment.

In addition, headache at the back of the head following fever could also result from increased intracranial pressure. It is important to seek timely medical evaluation for a thorough examination and to determine the underlying cause so that appropriate drug therapy can be selected.

After being scratched by a small hamster and receiving an injection, can I take fever-reducing medicine if I develop a fever?
If the fever exceeds 38.5°C, or is accompanied by significant discomfort such as headache, muscle aches, and fatigue, taking antipyretic medications (such as acetaminophen tablets or ibuprofen suspension) can help relieve symptoms and prevent potential adverse effects of high fever on the body. Antipyretics do not interact with vaccines administered after scratches or wounds, nor do they interfere with the vaccine's ability to induce an immune response; therefore, there is no need to worry about drug interactions.

Can I take a bath on the 8th day after receiving the MMR vaccine if I have a fever?
On the eighth day after receiving the MMR vaccine, whether one can take a bath during a fever should be determined based on the severity of the fever and overall physical condition. If the fever is mild and the person is in good spirits, a brief bath may be acceptable. However, if the fever is high or the person feels weak and lethargic, bathing should be avoided. When bathing, ensure the water temperature is comfortable—not too cold or too hot—keep the bathing time short, dry the body and hair promptly afterward, and take proper measures to stay warm.
