It sounds like you’re experiencing a concerning rash that could be related to a few different factors, including a possible allergic reaction or exposure to chickenpox. Here’s a breakdown of what might be happening and what you can do about it.

Main Points

1. Your rash may be a reaction to medication, food, or a virus (like chickenpox).
2. Watch for certain symptoms that could indicate a need for urgent care.
3. Take steps to manage your symptoms and monitor for changes.

Explanation

The rash you describe, with raised welts and itching, could indicate an allergic reaction to either the Nitrofurantoin antibiotic, the sushi you ate, or even a viral infection like chickenpox, especially since you were exposed to it recently. Allergic reactions can develop quickly after exposure and may worsen without treatment.

Next Steps

1. Monitor Symptoms: Keep track of how your rash develops over the next few days. Note the appearance, any new spots, and if you experience fever, chills, or worsening itching.

2. Symptom Relief: To help relieve itching and discomfort, consider using:

   • Antihistamines: Over-the-counter options like diphenhydramine (Benadryl) or cetirizine (Zyrtec) can help reduce itching.
   • Cool compresses: Apply cool, damp cloths to the affected areas for relief.
   • Moisturizers: Use fragrance-free creams to help soothe the skin.

3. Avoid Irritants: Stay away from scratching the rash, apply sunscreen to protect it from sun irritation, and refrain from using harsh soaps or lotions on the affected areas.

4. Watch for Severe Symptoms: If you experience severe itching, difficulty breathing, swelling of the face or throat, or if the rash expands significantly, it is crucial to seek urgent medical attention, as these could be signs of a serious allergic reaction.

5. Consult on Chickenpox Signs: If you develop flu-like symptoms, a fever, or if the rash looks fluid-filled (like blisters), it may indicate chickenpox, and professional evaluation would be more critical at that time.

Remember that your health and comfort are important, so keep an eye on your symptoms and take these steps to help manage the situation. If you have further concerns or if your symptoms worsen, seeking medical guidance would be appropriate.
