Arora's Assessment

Thank you for providing all the necessary information. Based on the symptoms and history you've shared, here's some advice that might help you understand what could be happening and what you can do:

What might be happening

Based on your symptoms of a bumpy, itchy rash that burns after scratching, along with headache, joint pain, upset stomach, and fatigue, here are some possible explanations:

  1. Contact Dermatitis: This is a common skin reaction to an irritant or allergen. Given your history of allergies to red meat and gluten, it's possible that you might have come into contact with something that triggered this reaction.

    • Treatment: Avoiding the irritant or allergen, using topical corticosteroids, and taking antihistamines can help manage symptoms.
  2. Eczema (Atopic Dermatitis): This chronic condition can cause itchy, inflamed skin. Stress and other factors can trigger flare-ups.

    • Treatment: Moisturizers, topical steroids, and avoiding known triggers can help manage eczema.
  3. Psoriasis: This is an autoimmune condition that causes red, scaly patches on the skin. It can be associated with joint pain (psoriatic arthritis).

    • Treatment: Topical treatments, phototherapy, and systemic medications can help manage psoriasis.
  4. Viral Exanthem: Some viral infections can cause a widespread rash along with systemic symptoms like headache, joint pain, and fatigue.

    • Treatment: Symptomatic treatment, such as rest, hydration, and over-the-counter pain relievers, can help.
  5. Drug Reaction: Although you mentioned not taking new medications, sometimes reactions can occur with existing medications.

    • Treatment: Discontinuing the offending drug (under medical supervision) and using antihistamines or corticosteroids can help.

What you can do

  1. Avoid Scratching: Scratching can worsen the rash and lead to infection. Try to keep your nails short and consider wearing gloves at night.
  2. Moisturize: Use a fragrance-free moisturizer to keep your skin hydrated.
  3. Cool Compresses: Applying cool, damp cloths to the affected areas can help soothe itching and burning.
  4. Over-the-Counter Treatments: Continue using antihistamines like Benadryl and hydrocortisone cream, but if they are not effective, consult a healthcare provider.
  5. Track Symptoms: Use MDandMe to journal your symptoms, track progress, and share this information with your healthcare provider.
  6. Avoid Known Allergens: Since you have allergies to red meat and gluten, ensure you are not consuming these or coming into contact with them.

What you should look out for

Seek medical attention if you experience any of the following:

  1. Severe Symptoms: If the rash spreads rapidly, becomes very painful, or shows signs of infection (such as pus, increased redness, or warmth).
  2. Systemic Symptoms: If you develop a high fever, difficulty breathing, or swelling of the face or throat.
  3. Persistent Symptoms: If the rash and other symptoms do not improve with over-the-counter treatments or continue to worsen.

Remember, while this advice can help you manage your symptoms, it is important to consult a healthcare professional for a formal diagnosis and appropriate treatment.
