Low-Grade Fever, Chills, Fatigue, and Headache Symptoms - Internal Medicine

Low-grade fever, chills, weakness, headache?


Hello, I have been experiencing a low-grade fever for three to four days (body temperature around 37.3-37.5°C).
I also have a headache, fatigue, and slight chills.
I took a home rapid test for COVID-19 yesterday, which came back negative, thus ruling out the possibility of a COVID-19 infection.
I would like to ask if excessive fatigue (going to bed around 3:30 AM), being in my ovulation period (I am currently in my ovulation phase), or stress could also cause the above symptoms? How should I alleviate them? Thank you!

Yu, 20~29 year old female. Ask Date: 2021/08/16

Hello, other viral infections, urinary tract infections, irregular lifestyle, high stress, and menstrual periods can all contribute to the symptoms mentioned above.
It is recommended to maintain a regular schedule, exercise, and have a balanced diet, as well as to drink plenty of water.
If fever persists, it is advisable to consult an infectious disease specialist to determine the cause of the fever.
Additionally, if the fever lasts for several days, it may be necessary to retest for COVID-19 and influenza.
Thank you for your inquiry.

Hello! It sounds like you are experiencing a combination of symptoms that can be quite concerning. Low-grade fever, chills, fatigue, and headache can arise from various causes, and understanding these symptoms is crucial for determining the appropriate next steps.

Firstly, a low-grade fever, defined as a body temperature between 37.3°C (99.1°F) and 38°C (100.4°F), can be a sign of your body fighting off an infection or inflammation. Since you have already tested negative for COVID-19, it is wise to consider other potential causes. Common viral infections, such as the flu or other respiratory viruses, could still be responsible for your symptoms, even if they are mild.

You mentioned that you have been experiencing fatigue and headaches, which can be linked to several factors, including stress, lack of sleep, and hormonal changes associated with your menstrual cycle, particularly during ovulation. Stress can lead to tension headaches and exacerbate feelings of fatigue. Additionally, sleep deprivation, such as going to bed at 3:30 AM, can significantly impact your overall health, leading to increased fatigue and headaches.

Hormonal fluctuations during the menstrual cycle can also contribute to physical symptoms. Many women experience headaches, fatigue, and mood changes during ovulation due to the rise and fall of estrogen and progesterone levels. These hormonal changes can affect your body's response to stress and overall energy levels.

To alleviate your symptoms, consider the following strategies:
1. Rest and Sleep: Prioritize getting adequate sleep. Aim for 7-9 hours of quality sleep each night. Establish a calming bedtime routine to help you wind down before sleep.

2. Hydration: Ensure you are drinking enough fluids. Dehydration can worsen headaches and fatigue. Aim for at least 8 glasses of water a day, and consider herbal teas or electrolyte drinks if you feel dehydrated.

3. Nutrition: Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help support your immune system and overall energy levels. Avoid excessive caffeine and sugar, which can lead to energy crashes.

4. Stress Management: Engage in stress-reducing activities such as yoga, meditation, or deep-breathing exercises. Regular physical activity can also help reduce stress and improve your mood.

5. Monitor Symptoms: Keep track of your symptoms. If your fever persists beyond a few days, or if you develop new symptoms such as a high fever, severe headache, or difficulty breathing, it is essential to seek medical attention.

6. Consult a Healthcare Provider: If your symptoms do not improve with self-care measures or if you have concerns about your health, it is advisable to consult a healthcare professional. They may recommend further evaluation or tests to rule out any underlying conditions.

In summary, while your symptoms could be related to fatigue, hormonal changes, or stress, it is essential to monitor your condition closely. If your symptoms persist or worsen, do not hesitate to seek medical advice. Your health is paramount, and a healthcare provider can help you navigate these symptoms effectively. Take care!
