Persistent Severe Itching, Red Patches, Bumps: What's Wrong?

I'm sorry to hear you're experiencing such intense and persistent itching. This sounds very uncomfortable and distressing. While I can't provide a definitive diagnosis, I can share some information about potential causes of widespread itching:

• Allergic reactions (to food, medication, or environmental factors)
• Eczema or atopic dermatitis
• Psoriasis
• Hives (urticaria)
• Dry skin (xerosis)
• Scabies (mite infestation)
• Fungal infections
• Thyroid problems
• Liver or kidney issues
• Certain medications

Given the duration and severity of your symptoms, I strongly recommend seeing a dermatologist as soon as possible. They can perform a thorough examination and possibly run tests to determine the underlying cause.

In the meantime:

• Try to avoid scratching, as this can lead to skin damage and infection
• Use cool compresses to soothe the skin
• Apply unscented, hypoallergenic moisturizer
• Take lukewarm (not hot) showers
• Wear loose, breathable clothing
• Consider using over-the-counter antihistamines (but consult a pharmacist first)

Remember, persistent and severe itching like you're describing warrants professional medical attention. Your comfort and health are important. Take care, and I hope you find relief soon.
