Every year, flu season makes its way through New Jersey, and while most people expect the usual fever and body aches, the earliest signs often go unnoticed. By the time symptoms worsen, the virus has already taken hold — making recovery harder and increasing the risk of spreading it to others.

Recognizing the early flu symptoms gives you a head start in managing the illness and protecting those around you. At Care Station Medical Group, our providers see these early signs every season. Here’s what you should watch for, and when it’s time to come in for care.

Persistent Fatigue That Feels “Different”

Feeling tired after a busy day or a poor night’s sleep is normal. But fatigue caused by the flu feels very different. It tends to come on suddenly — even before other symptoms appear — and doesn’t improve with rest. You might feel drained, weak, or like you’re “coming down with something,” even if you don’t have a fever yet.

This exhaustion happens because your body is already fighting off an infection. The immune system releases chemicals to combat the virus, which can leave you feeling wiped out.

If this tiredness lingers for more than a day or two or starts affecting your ability to do everyday tasks, it’s worth getting checked out. Fatigue alone doesn’t always mean you have the flu, but combined with a mild fever or muscle aches, it’s often one of the earliest warning signs.

Sudden Body Aches and Joint Pain

Another common early sign people tend to brush off is sudden, unexplained body aches. You might think you overdid it at the gym or slept in an awkward position, but the discomfort that comes with the flu usually affects several areas at once — shoulders, back, legs, or joints. These aches occur as your body responds to inflammation and the release of immune chemicals. It’s your body’s way of saying it’s fighting something.

If these aches appear alongside fatigue or chills, don’t ignore them. Over-the-counter pain relievers can help with mild discomfort, but persistent or worsening aches may point to the flu or another viral infection.

Scratchy Throat or Dry Cough That Worsens Quickly

A mild sore throat or occasional cough can feel like no big deal — especially during cold weather or allergy season. But if your throat irritation seems to appear overnight or your cough worsens quickly, it could be the start of the flu.

Flu-related coughs often feel dry and deep, not like the tickly coughs that come with a cold. You might also notice your voice becoming hoarse or your throat feeling raw. These symptoms can show up early and progress within hours.

It’s time to visit urgent care if:

• Your cough starts interfering with sleep.
• You develop a fever.
• You feel pressure in your chest or shortness of breath.

Mild Fever or Chills That Come and Go

With the flu, fever can start low and fluctuate throughout the day. Chills may come and go, making you feel alternately hot and cold. For most healthy adults, this might not seem serious, but for children, older adults, or those with chronic conditions, a rising fever can quickly become concerning.

If you notice your temperature climbing above 100°F or the fever lasts more than a couple of days, visit one of Care Station’s locations across New Jersey. Our team can evaluate your condition, perform a flu test, and help control your fever safely. Prompt care also helps prevent complications like dehydration or pneumonia, which can develop if the flu isn’t managed properly.

Headache and Eye Pressure

Headaches are another early flu symptom that people often overlook or blame on stress. However, headaches linked to the flu tend to feel deeper and more intense. You might feel pressure behind your eyes, around your temples, or across your forehead.

This happens because the flu virus can inflame sinuses and blood vessels in the head, causing discomfort. Dehydration, which often accompanies the flu, can make the pain worse. If your headache doesn’t improve with rest, hydration, or mild pain relievers — or if it’s paired with fatigue, fever, or congestion — it’s worth having it checked out.

When to See Your Doctor

The flu can develop quickly, and knowing when to seek care makes a big difference in recovery time. You should come in if you experience:

• Fever lasting longer than two days
• Difficulty breathing or chest discomfort
• Severe fatigue that affects your daily routine
• Persistent vomiting or signs of dehydration
• Symptoms that worsen instead of improving

How to Protect Yourself During Flu Season

While early detection helps, prevention is always the best defense. You can lower your flu risk with a few simple habits:

• Get your flu shot: It’s the most effective way to prevent infection and serious illness. Care Station offers flu vaccinations for individuals and families.
• Wash your hands regularly: Soap and water go a long way in stopping germs from spreading.
• Stay hydrated and well-rested: A healthy immune system handles infections better.
• Avoid close contact with sick individuals: Especially in enclosed or crowded spaces.
• Clean frequently touched surfaces: Germs can linger on doorknobs, phones, and countertops.
