### What is Eczema?
Eczema is a common skin condition that causes itchiness, rashes, dry patches, and sometimes infections. It is a type of dermatitis, which means inflammation of the skin. The most common form of eczema is atopic dermatitis, often linked with other allergic conditions like asthma and hay fever.

2. **Contact Dermatitis**: Caused by contact with irritants or allergens.
3. **Dyshidrotic Eczema**: Characterized by tiny blisters on the hands and feet.
4. **Neurodermatitis**: Causes intensely itchy patches, often linked with stress or anxiety.
5. **Nummular Eczema**: Coin-shaped spots that appear after skin injuries.
6. **Seborrheic Dermatitis**: Affects oily areas like the scalp, causing dandruff.
7. **Stasis Dermatitis**: Occurs in people with poor blood flow, usually in the lower legs.

- **Adults**: Rash on the face, backs of knees, wrists, hands, or feet. Skin may be dry, thick, or scaly.
### Diagnosis
Doctors diagnose eczema by examining the skin and asking questions about symptoms. Allergy tests may be conducted to identify triggers.
### Treatment
