Experiencing Side Effects From a Tetanus Booster: Is This Typical?

8/1/2025, 2:20:19 PMMale25-34

Hello everyone! Recently, I received a tetanus toxoid booster shot because of a cut I sustained while traveling abroad, where I suspect some dust may have gotten into it. Within less than 24 hours post-vaccination, I developed a fever reaching 38.8°C (101.8°F). It has been approximately 36 hours, and I am still experiencing a fever of around 38.2°C (100.8°F). Alongside the fever, I'm dealing with a headache, muscle soreness, extreme tiredness, and an overall sense of illness. Additionally, I've noticed a mild cough forming, which I think could be related to the air conditioning here, as I’m currently in a tropical climate and not accustomed to such conditions. Should I be concerned about these symptoms, or could this be a normal reaction to the vaccination? Thank you!

It's understandable to be concerned about your symptoms following a tetanus booster shot. It's common to experience mild to moderate side effects after vaccinations, including fever, headache, muscle soreness, and fatigue. These reactions are typically your body's natural response to building immunity and can last a few days.

Explanation: After receiving the tetanus toxoid booster, many people experience symptoms like fever and body aches as their immune system reacts to the vaccine. The fever you're experiencing (38.8°C or 101.8°F) can occur within a day of vaccination and is generally not a cause for alarm unless it persists or worsens significantly. Your mild cough may be related to environmental factors, such as air conditioning, rather than the vaccine itself.

Next Steps:

  1. Monitor Your Symptoms: Continue to keep an eye on your fever and overall condition. It's helpful to track any changes in symptoms over the next few days.

  2. Manage Fever and Discomfort:

    • Stay hydrated by drinking plenty of fluids.
    • Take over-the-counter medications like acetaminophen or ibuprofen to help reduce fever and alleviate aches if needed.
  3. Rest: Ensure you're getting enough rest to help your body recover.

  4. Address the Cough: If your cough worsens or if you develop other troubling symptoms (like difficulty breathing, chest pain, or high fever persisting beyond a few days), consider seeking medical advice.

  5. Seek Support: If you're feeling very unwell or your symptoms don't improve in a few days, it’s always a good idea to reach out for further evaluation.

In most cases, these side effects resolve on their own, but you should prioritize your comfort and seek help if you have any concerns. Take care, and let me know if you have any more questions!

Concern Over Double Dosage of Clonidine

My son, who is 19 years old, typically takes a nightly dose of 0.3mg of Clonidine along with 6mg of Melatonin. He is diagnosed with severe Autism, so either my husband or I are responsible for giving him his medication. Unfortunately, tonight he received an accidental double dosage of both medications. He stands at 6 feet 4 inches tall and weighs 325 pounds. Given the situation, should we seek immediate medical attention at urgent care? I am particularly worried about the possibility of his heart rate and blood pressure decreasing significantly throughout the night. I appreciate any advice you can provide.

Concerns Regarding Recurrent Fevers in Young Child

Hello, I’m reaching out about my 2-year-old daughter, who experiences fevers approximately every 4 to 6 weeks. Typically, these fevers are accompanied by symptoms such as a runny nose and cough, with temperatures ranging from 101 to 103 degrees. Fortunately, she's responsive to Motrin. There are no visible issues like rashes, bruising, night sweats, or swollen lymph nodes, and she generally remains cheerful, active, and engaged in play. During episodes of higher fever, she may feel chills and tends to rest more but soon resumes her usual activities. Her appetite fluctuates, as she has always been quite selective with food. Back in November, we visited the doctor because she had a fever lasting around four days along with a runny nose. Given her symptoms, they conducted a Complete Blood Count (CBC), and now I’m a bit anxious about the results since they indicate atypical lymphocytes. I’m wondering if this suggests any serious health issues. Below are her CBC results: - WBC (White Blood Cells): 17.7 - RBC (Red Blood Cells): 3.31 - Hemoglobin (Hgb): 9.0 - Hematocrit (Hct): 26.3% - MCV: 79.4 - MCH: 27.2 - MCHC: 34.2 - RDW: 12.6% - Platelet Count: 185 - MPV: 6.0 Differential count shows: - Neutrophils: 37% - Lymphocytes: 53% - Monocytes: 5% - Eosinophils: 3% - Basophils: 1% - Atypical Lymphocytes: 5% Additionally, I’ve kept a log of her fevers: - Nov 6, 2024 – 4 days - Dec 24, 2024 – 2 days - Jan 4, 2025 – 3 days - Jan 23, 2025 – 3 days - Feb 2, 2025 – 3 days - Mar 7, 2025 – 2 days - May 11, 2025 – 1 day - Jul 4, 2025 – 3.5 days - Jul 15, 2025 – 1 day - Jul 21, 2025 – 1 day - Jul 31, 2025 – Ongoing (1+ days)

Seeking Guidance on Sudden Leg Swelling

Hello! My father-in-law has experienced some unusual swelling over the past few days, starting from his knee and progressing down to his foot. We're currently situated in California. He is a 65-year-old male weighing 200 pounds. The issue began yesterday, initially manifesting as a swelling that felt like a fluid-filled ball around his knee. By last night, he noticed significant swelling in his ankle, which has since extended down to his foot. We've observed some bruising at the base of his heel, but there was no trauma or injury; he simply noticed this upon waking up. We would greatly appreciate any insights into what might be causing this condition. His medical history includes taking medication for high blood pressure; however, he recently underwent a scan with his cardiologist and received a clean bill of health regarding his heart. Apart from his two daily blood pressure medications, he has no other ongoing health issues or medication. His blood pressure can be elevated at times, though it has never reached critical levels. Overall, he maintains a healthy lifestyle, engaging in regular exercise, abstaining from alcohol and tobacco, and following a nutritious diet.
