When dealing with skin abnormalities such as clustered blisters on the limbs, it is crucial to understand the underlying causes, potential treatments, and the interactions between medications. Based on the information provided, it seems you are experiencing a worsening condition characterized by redness and the proliferation of blisters, which can be indicative of several dermatological issues, including allergic reactions, infections, or autoimmune conditions.

The use of hydrocortisone 1% cream, a topical corticosteroid, is a common first-line treatment for inflammatory skin conditions. It works by reducing inflammation, redness, and itching. However, while it may provide temporary relief, it is essential to consider whether this treatment is appropriate for your specific condition. If the blisters are due to an infection (such as a viral or bacterial infection), corticosteroids may not be the best choice, as they can suppress the immune response and potentially worsen the infection.

In your case, the rapid expansion of the red, blistering areas suggests that the condition may be more severe than initially thought. It is advisable to seek immediate medical attention from a dermatologist who can provide a thorough examination and possibly perform diagnostic tests, such as skin scrapings or biopsies, to determine the exact cause of your symptoms. This is particularly important if you notice any signs of infection, such as increased pain, warmth, or pus.

In the meantime, here are some general recommendations for managing your symptoms:
1. Avoid Irritants: Keep the affected areas clean and avoid any known irritants or allergens that may exacerbate the condition. This includes harsh soaps, fragrances, and certain fabrics.

2. Moisturize: While you may have concerns about the interaction between topical steroids and moisturizers, applying a gentle, fragrance-free moisturizer can help maintain skin hydration and barrier function. It is generally recommended to apply moisturizers after bathing to lock in moisture.

3. Cool Compresses: Applying cool, damp cloths to the affected areas can help soothe irritation and reduce inflammation.

4. Avoid Scratching: It is crucial to avoid scratching the blisters, as this can lead to secondary infections and further complications.

5. Follow-Up Care: Since you are returning to Taiwan soon, it would be wise to schedule an appointment with a dermatologist as soon as you arrive. They can reassess your condition and adjust your treatment plan accordingly.

6. Medication Review: If you have been prescribed other medications or treatments, discuss these with your healthcare provider to ensure there are no contraindications or interactions that could be affecting your skin condition.

In conclusion, while hydrocortisone cream may provide some relief, it is essential to have a comprehensive evaluation to determine the most appropriate treatment for your specific condition. The worsening of your symptoms warrants immediate attention, and a dermatologist will be best equipped to provide the necessary care and guidance. Remember, early intervention can often lead to better outcomes in dermatological conditions.
