What might be happening

Based on the information you've provided, possible explanations for your symptoms include:

  • Allergic Contact Dermatitis: This is a skin reaction following contact with a substance that the immune system recognizes as foreign, such as certain plants (like poison ivy or poison oak). It can cause severe itching and the sensation of insects crawling on the skin, although a visible rash is usually present.

    • Treatment typically involves avoiding the allergen, applying topical creams to relieve itching, and taking oral antihistamines.

  • Seasonal Allergies (Hay Fever): Your symptoms seem to occur seasonally, which could suggest an allergic reaction to airborne substances like pollen. This can cause severe itching, although it typically also involves symptoms like sneezing, runny or stuffy nose, and itchy or watering eyes.

    • Treatment usually involves avoiding the allergen when possible and taking antihistamines to control symptoms.

  • Scabies: This is an infestation by a tiny mite that burrows into the skin, causing intense itching and the sensation of insects crawling on the skin. However, it typically also involves a visible rash and small bumps or blisters.

    • Treatment involves medications that kill the scabies mites and their eggs.

  • Stress or Anxiety: These can sometimes cause physical symptoms like itching, although this is usually not the only symptom.

    • Treatment involves addressing the underlying stress or anxiety, which may involve therapy, medication, or other strategies.

Please note that these are just possibilities, and the actual cause of your symptoms could be something else. It's important to see a healthcare provider for an accurate diagnosis and appropriate treatment.

What you can do

  1. Continue taking over-the-counter allergy medication as directed on the package, if it seems to help.
  2. Try applying a cool, damp cloth to the itchy areas, or taking a cool bath or shower.
  3. Avoid scratching as much as possible, as this can worsen the itching and even cause infection.
  4. Try to avoid exposure to plants or other potential allergens, especially in wooded areas.
  5. Consider seeking help for stress or anxiety, such as talking to a counselor or therapist, or trying relaxation techniques like deep breathing or yoga.

What you should look out for

Please seek immediate medical attention if:

  • The itching becomes unbearable or significantly interferes with your daily activities.
  • You develop other symptoms, such as difficulty breathing, swelling of the face or lips, or a visible rash or hives.
  • The itching doesn't improve after a few days, or it gets worse.
  • You notice signs of infection, such as increased redness, swelling, pain, or pus.

Remember, while I strive to provide accurate information, I'm not a doctor and this advice should not replace a consultation with a healthcare provider.
