What might be happening

Based on the information you have provided, here are some possible explanations for your symptoms:

• Chronic Urticaria (Hives): This condition can cause itchy welts that appear and disappear over time. It can be triggered by temperature changes, stress, or other factors. Chronic urticaria can sometimes cause blisters under the skin when scratched.

  • Treatment: Antihistamines are commonly used to manage symptoms. In some cases, doctors may prescribe stronger medications or recommend lifestyle changes to avoid triggers.

• Dermatographia: This is a condition where minor scratches turn into temporary but significant reactions, such as red lines or welts. It can be triggered by stress and changes in temperature.

  • Treatment: Antihistamines can help manage symptoms. Avoiding scratching and using gentle skin care products can also be beneficial.

• Eczema (Atopic Dermatitis): This condition can cause itchy, inflamed skin that feels like reptile skin. It can be triggered by environmental factors, stress, and temperature changes.

  • Treatment: Moisturizers, topical corticosteroids, and avoiding known triggers can help manage symptoms.

• Contact Dermatitis: This is an inflammatory reaction to substances that come into contact with your skin. It can cause itching and blisters.

  • Treatment: Identifying and avoiding the irritant is key. Topical corticosteroids and antihistamines can help manage symptoms.

What you can do

While it's important to consult a healthcare professional for a formal diagnosis and treatment plan, here are some steps you can take to manage your symptoms:

1. Avoid Triggers: Try to minimize exposure to extreme temperature changes and manage stress through relaxation techniques like deep breathing or meditation.
2. Skin Care: Use gentle, fragrance-free moisturizers and soaps to avoid irritating your skin further. Keeping your skin hydrated can help reduce itching.
3. Over-the-Counter Medications: Antihistamines like cetirizine (Zyrtec) or loratadine (Claritin) can help reduce itching. Always follow the dosage instructions on the package.
4. Cool Compresses: Applying a cool, damp cloth to the itchy areas can provide temporary relief.
5. Avoid Scratching: Try to avoid scratching the itchy areas to prevent blisters and further irritation. Keeping your nails short can help minimize damage if you do scratch.
6. Journal Your Symptoms: Use MDandMe to journal your symptoms, track progress, and get insights. This can be helpful information to share with your healthcare provider.

What you should look out for

Seek medical attention if you experience any of the following:

• Severe or Worsening Symptoms: If your itching becomes unbearable or your skin condition worsens, consult a healthcare professional.
• Signs of Infection: If you notice redness, swelling, or pus in the areas where you have blisters, seek medical attention as this could indicate an infection.
• New Symptoms: If you develop new symptoms such as difficulty breathing, swelling of the face or throat, or a rapid heartbeat, seek immediate medical attention as these could be signs of a severe allergic reaction.

Remember, while this advice can help manage your symptoms, it's important to consult a healthcare professional for a formal diagnosis and treatment plan.
