There has been no exposure to others with similar symptoms, and this is the first occurrence of such itching.

What might be happening

Based on the symptoms you've described, here are a few possible explanations:

  • Dermatographia (Skin Writing): This is a condition where lightly scratching your skin causes raised, red lines where you've scratched. It's often harmless and can be triggered by stress, infections, or medications. The symptoms you describe, such as itchy skin and the appearance of lines after scratching, align with this condition.

    • Treatment typically involves antihistamines to reduce itching and inflammation. It's important to avoid scratching to prevent further irritation.

  • Allergic Reaction or Sensitivity: Although you haven't changed products recently, it's possible to develop sensitivities over time. This could be related to your birth control, although it's less common.

    • Treatment involves identifying and avoiding the trigger, and using antihistamines or topical creams to manage symptoms.

  • Dry Skin or Eczema: These conditions can cause itchy, irritated skin. Changes in weather or humidity can exacerbate these symptoms.

    • Treatment includes moisturizing regularly and using gentle, fragrance-free products.

What you can do

  1. Avoid Scratching: Try to avoid scratching your skin, as this can worsen the irritation. Keeping your nails short can help minimize damage if you do scratch.

  2. Moisturize Regularly: Use a gentle, fragrance-free moisturizer to keep your skin hydrated. Applying it after a shower can help lock in moisture.

  3. Consider Antihistamines: Over-the-counter antihistamines may help reduce itching. However, it's best to consult with a healthcare provider before starting any new medication.

  4. Track Your Symptoms: Use MDandMe to journal your symptoms, track any changes, and note any potential triggers. This information can be helpful for your healthcare provider.

What you should look out for

  • Seek Medical Attention If:
    • Your symptoms continue to worsen or do not improve with self-care measures.
    • You develop additional symptoms, such as swelling, difficulty breathing, or a rash that spreads rapidly.
    • You experience any side effects from medications you take to manage your symptoms.

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