[52F] Experiencing sore throat, nasal congestion, and body chills

What might be happening

Based on the symptoms you've described, you may be experiencing:

• A viral upper respiratory infection: This is commonly known as the common cold. The symptoms usually include a sore throat, nasal congestion, and a cough. The weakness and chills you're experiencing could be due to the body's response to the virus. The coated tongue could also be a result of mouth breathing due to nasal congestion.

  • Treatment typically involves rest, hydration, and over-the-counter remedies to alleviate symptoms.

• Allergic reaction or dermatitis: The red, hot rash you described could be due to an allergic reaction or dermatitis, especially since you mentioned it improved slightly with Zyrtec, an antihistamine. This could be due to a new environment or substance you've come into contact with recently, such as during your visit to the hotel and water park.

  • Treatment typically involves avoiding the allergen or irritant and using over-the-counter or prescription creams to alleviate symptoms.

• Hashimoto's thyroiditis: This is an autoimmune condition where the body's immune system attacks the thyroid, leading to hypothyroidism. You mentioned you were diagnosed with this recently. Some of your symptoms, such as feeling cold and weak, could be related to this condition.

  • Treatment typically involves hormone replacement therapy, which you're currently on (NP Thyroid).

What you can do

1. Continue to rest and stay hydrated. Over-the-counter remedies can help alleviate symptoms of a cold.
2. Continue taking Zyrtec as directed for your rash. If the rash worsens or doesn't improve, seek medical attention.
3. Monitor your thyroid symptoms and discuss them with your doctor, who may adjust your medication dosage if necessary.
4. If your symptoms worsen or you develop new symptoms, seek medical attention.

What you should look out for

• Difficulty breathing or shortness of breath
• High fever (over 102°F)
• Severe headache or neck stiffness
• Rash that spreads rapidly or is accompanied by other severe symptoms
• Severe weakness or fatigue that prevents you from performing daily activities
