Racing Heart, High Fever, and Dizziness: All Tests Negative
Age 25, male. No prior health concerns, not on any medication, no known allergies, and no history of substance abuse. I do drink alcohol occasionally. This morning around 4 AM, I awoke to an alarming sensation of my heart racing. Upon attempting to rise from bed, I immediately felt dizzy and unstable, so I quickly sat back down, just managing to avoid fainting. It was then I decided to call emergency services. The ambulance team and the emergency room staff conducted a full examination, which included checking my vital signs, an EKG, and blood sugar levels, but they found little of concern. They performed additional tests including a blood panel and a chest x-ray, both of which yielded normal results. However, the hospital did note that I had a fever of 103 degrees. They administered IV fluids along with Toradol, which effectively lowered both my fever and heart rate. Although they suspected my elevated pulse rate was linked to the fever, they could not ascertain the initial cause of the fever itself. I was advised to take Ibuprofen, stay hydrated, and to return if I experienced dizziness again or if my fever persisted after three days. Throughout this ordeal, I have not exhibited any typical signs of illness, such as nausea, vomiting, a cough, sore throat, or nasal congestion. I am curious about what might have caused such a sudden spike in my temperature and heart rate.

It sounds like you've experienced a very concerning episode with a racing heart, high fever, and dizziness, especially since you're otherwise healthy. Given that tests returned normal results, this may indicate a few potential non-infectious causes for your symptoms.
Understanding Your Situation: Your high fever and racing heart might be linked to various factors, including:
- Viral Infections: Sometimes, viral infections can cause fever and elevated heart rate without the common symptoms like cough or sore throat.
- Dehydration or Electrolyte Imbalance: Even minor dehydration can cause dizziness and a rapid heart rate.
- Anxiety or Stress Response: High emotional stress can trigger a racing heart and dizziness, even in the absence of physical illness.
- Other Conditions: Less common conditions might cause a fever and elevated pulse, but given your tests, these appear unlikely.
Next Steps for Management:
-
Monitor Your Fever: Keep track of your temperature as instructed. If it persists beyond three days or exceeds 103 degrees, or if you develop new symptoms, it is important to seek further medical evaluation.
-
Stay Hydrated: Drink plenty of fluids, especially water, to stay hydrated. This can help in reducing dizziness and supports overall recovery.
-
Use Ibuprofen as Directed: Continue to take the Ibuprofen to manage your fever and any discomfort, following the dosage instructions provided by your healthcare team.
-
Rest and Recovery: Ensure you get adequate rest. Avoid strenuous activities until you feel completely normal.
-
Keep a Symptom Journal: Note any changes, especially if symptoms reappear, or new symptoms develop. This can help you and healthcare providers identify any patterns.
-
Evaluate Stress Levels: If stress or anxiety could be contributing to your symptoms, consider relaxation techniques such as deep breathing, meditation, or gentle yoga.
Be mindful of your body and reach out to healthcare services again if you experience a recurrence of dizziness, severe symptoms, or if your fever fails to improve. Your health is the priority, and these steps can help you manage your current situation effectively.

Concerns About Measles Exposure After Outbreak at Work
We have not experienced any symptoms, and both of us received our vaccinations during childhood. Recently, one of our coworkers was identified as the initial case of measles within the state and has since been hospitalized. The workplace is a smaller manufacturing facility, employing around 30 people, many of whom are unvaccinated. Given this situation, do we need to take any specific actions? Is it still possible for us to transmit the virus despite being vaccinated? We are uncertain about the necessary safety measures to adopt. Our employer hasn't communicated anything regarding the outbreak; we only learned about it when we saw our workplace mentioned in the news.
Is a Red Spotted Uvula and Fever Enough to Visit the Clinic?
I am a 30-year-old woman, standing at 5'2" and weighing 280 lbs. I smoke marijuana but do not use any nicotine or vaping products. On Wednesday morning, I woke up experiencing a painful throat. The discomfort is more pronounced when I first wake up but tends to ease up later in the day. I’ve been experiencing minimal coughing, some post-nasal drip, and a fever fluctuating between 100.8°F and 101.4°F, alongside significant fatigue. Today, I also developed headaches. I suspect that my lymph nodes might be swollen, but I'm not a health expert, so I can't be certain. I have been checking my temperature rectally, as my mother mentioned that I typically don't exhibit typical fever symptoms outwardly. Is it advisable for me to see a doctor? I worry about taking up a physician's time if this is just a viral infection. No one else at home or any of my coworkers are showing symptoms of illness.
Managing Fever with NAFLD
At 31 years old, I've been dealing with some health challenges. In September, I discovered I had non-alcoholic fatty liver disease (NAFLD) due to abnormal enzyme levels revealed in an ultrasound. Although my latest results show a decrease, my enzyme levels remain somewhat elevated, with a moderate accumulation of fat noted. My doctor advised against using acetaminophen for pain relief. Interestingly, my father, who has a more severe case with significantly higher enzyme levels, was allowed to use acetaminophen but not ibuprofen. Since my diagnosis, I've avoided both medications. However, I am currently suffering from a cold accompanied by a fever of 100.2 degrees, which is quite uncomfortable. I reached out to my healthcare provider for advice, but since it's late at night, I probably won't receive a response until tomorrow. For context, I am on a treatment regimen that includes 20mg of Abilify and 50mg of Pristiq, and I do not consume alcohol. Today, I also took Sudafed PE twice to help with my symptoms.
Scaly Rash Emerging Near Cat Bite
I am a 30-year-old female, and I recently noticed a small, red rash that is raised and scaly around a bite I received on my calf from a fully vaccinated indoor cat. This rash is not warm, swollen, painful, or itchy and emerged roughly a week after the incident. The outline of the rash is distinctly defined, resembling a diamond shape, and is approximately the size of my thumbprint. I have a history of eczema from my childhood, and I have also been diagnosed with combined symptoms of Lupus and Scleroderma, in addition to mucous membrane pemphigoid; however, all of these conditions are currently well managed. The rash does not appear to be infected, and I’ve come across information suggesting that skin injuries can lead to the development of autoimmune sores in the same area. What might be the cause of this rash?
High Fever of 104°F in a Child
An 8-year-old girl, approximately 4 feet tall and weighing around 50 pounds, has been unwell for the past two days. On the first day, her temperature fluctuated between 99°F and 101°F. However, by midday on the second day, her fever escalated to 104°F and has remained above 103°F for the last seven hours, despite alternating between children's Tylenol and Motrin every three hours. She is experiencing fatigue, a sore throat, and a raspy cough. After receiving a dose of Tylenol at midnight, her temperature was recorded at 104.1°F. I am uncertain if this situation necessitates a visit to the emergency room or if I should contact her doctor in the morning. Thank you for your guidance.
