A sudden fever, body aches, and exhaustion can leave you wondering whether you have the flu, a cold, or another illness. Knowing when to contact your primary care provider can help you get appropriate care.
Recognizing Common Flu Symptoms
Flu symptoms often begin suddenly and may include:
- Fever or chills, although not everyone develops a fever
- Cough, sore throat, or a runny or stuffy nose
- Muscle aches and headaches
- Significant tiredness
- Vomiting or diarrhea, which are more common in children
Flu, COVID-19, and other infections can cause similar symptoms. Your provider may recommend testing when it would help guide your care.
When to Contact Your Provider
Call promptly if you develop flu symptoms and are pregnant, age 65 or older, or have conditions such as asthma, diabetes, heart disease, or a weakened immune system. People at higher risk should seek advice even when symptoms seem mild.
You should also contact a provider if symptoms are severe, your fever persists, or an existing health condition gets worse.
Prescription antiviral medicines work best when started within the first two days of symptoms. Treatment may still help later, especially if you are at higher risk or have severe or worsening illness. Do not assume it is too late to ask about treatment.
What Happens During a Sick Visit?
Your provider will ask about your symptoms, when they began, your medications, and your medical history. They may check your vital signs and examine your throat, ears, and lungs.
Depending on the findings, your care plan may include testing, prescription medication, home-care instructions, or further evaluation. Antibiotics do not treat influenza itself, although they may be needed for certain bacterial complications.
Recovering at Home
For mild illness, rest and fluids can support recovery. Ask your provider or pharmacist which over-the-counter medicines are appropriate, especially if you have other health conditions or take prescription medications.
Stay home and away from others while sick. In general, return to normal activities once your symptoms have been improving overall and you have been fever-free without fever-reducing medicine for at least 24 hours. Take extra precautions for the next five days, such as wearing a well-fitting mask, improving ventilation, and limiting close contact with vulnerable people. Ask your provider about guidance for your circumstances.
When to Seek Emergency Care
Get medical attention right away for warning signs such as:
- Difficulty breathing
- Persistent chest or abdominal pain or pressure
- Persistent dizziness, confusion, or difficulty staying awake
- Not urinating or other signs of serious dehydration
- Severe weakness or unsteadiness
- Fever or cough that improves and then returns or worsens
Call 911 for severe or life-threatening symptoms. Do not wait for an office appointment.
Flu Prevention and Scheduling Care
Annual flu vaccination helps reduce the risk of flu and serious complications. Total Family Care does not provide vaccines in the office. Contact a pharmacy or another vaccination provider.
