It sounds like you're experiencing distressing skin reactions when visiting your parents' home, and your symptoms are significant and uncomfortable. It’s great that you’re seeking clarity about possible triggers and preventive measures.

Main Points:

• Your symptoms—large, warm, elevated welts that itch and bruise—may have several possible causes.
• Possible triggers could include contact allergens, environmental factors, or even insect activity (like the carpet beetle you found).
• It's crucial to take immediate steps to reduce exposure to potential triggers and soothe your skin.

Explanation:

The welts you're describing, especially given their size and inflammatory nature, could indicate an allergic reaction or irritant contact dermatitis. Since you've encountered a carpet beetle larva, it’s possible that you could be reacting to something related to that or something else in your parents' home. Although carpet beetle dermatitis tends to show small, itchy bumps, individual responses can vary widely.

Other factors to consider include:

• Laundry Detergents or Fabric Softener: Sometimes, the chemicals in laundry products can cause skin reactions.
• Pets: If your parents have pets, dander can also trigger allergic reactions.
• Dust Mites: These are common in bedding and carpets and can also lead to skin issues.

Next Steps:

1. Inspect the Environment:

   • Check for potential allergens: Examine the bedding (including pillowcases and blankets), carpets, and any common surfaces for dust and allergens.
   • If there are pets, consider whether they might be shedding allergens.

2. Try Barrier Methods:

   • Use hypoallergenic bed linens and pillowcases. Look for ones specifically labeled for sensitive skin.
   • Consider using protective barriers, like a mattress cover that reduces dust mite exposure.

3. Maintain a Skin Care Routine:

   • Apply a stronger anti-itch cream (like a higher strength hydrocortisone, if safe) or consider over-the-counter antihistamines to help alleviate itching before going to bed.
   • Moisturize your skin regularly, as keeping your skin well-hydrated can help reduce irritation.

4. Document Your Reactions:

   • Keep track of when and where the welts appear, and any potential exposures (including changes in your environment). This can help identify patterns or specific triggers.

5. Consider Air Quality:

   • If possible, use an air purifier that can help filter out allergens from the air, particularly in the bedroom.

If your symptoms continue or worsen despite these efforts, further investigation into potential allergens or irritants in your parents' home may be necessary. I encourage you to closely monitor your reactions as you implement these changes, and keep a record that you can refer back to if needed.
