* Scabies: Intense itching, especially at night, is the hallmark of scabies. The mites burrow under the skin, leaving tiny, raised lines or bumps that can become crusty, especially after scratching.
* Eczema (Atopic Dermatitis): This can cause dry, itchy, and inflamed skin. Scratching can lead to open sores that crust over.
* Fungal Infection (e.g., Ringworm): Ringworm can appear as a raised, scaly, circular rash with a central clearing.
* Impetigo: A bacterial skin infection that often starts with small blisters that burst and leave honey-colored crusts.
It's crucial to see a doctor or dermatologist for a diagnosis and appropriate treatment. Self-treating could worsen the condition or delay proper care.
