The causes of itchy hands and feet that worsen with scratching can be varied, mainly including the following:
1. **Dry skin**: When the skin becomes excessively dry, it easily loses moisture, its barrier function weakens, and itching may develop. Scratching may exacerbate these symptoms.
2. **Allergic reactions**: Allergies to substances such as detergents, cosmetics, or certain metals can cause redness, rash, and itching at the contact site. Scratching can make these symptoms worse.
3. **Fungal infections**: Fungal infections such as athlete's foot or hand fungus can also cause itchy hands and feet. Scratching may worsen symptoms and may be accompanied by flaking skin, blisters, and cracks.
4. **Skin inflammation**: Conditions such as eczema or neurodermatitis can cause severe itching. Scratching not only fails to relieve the itch but may also worsen the inflammation.
5. **Systemic diseases**: Systemic conditions such as diabetes may also lead to skin changes on the hands and feet, causing itching.
If discomfort persists, prompt medical consultation is recommended so that a specialist can make an accurate diagnosis and provide appropriate treatment based on individual circumstances.
