Eczema is a somewhat common skin condition where the skin can become very inflamed, being itchy and red, and often becoming rough and cracked. Eczema is also typically used to refer to atopic dermatitis (meaning the inflammation of the skin), which is by far the most common form of eczema. It can also be used to describe most common skin conditions that produce a rash or other rash-like symptoms. Some people who have eczema may have it for their entire lives, while many who have eczema as children may outgrow it by the time that they reach adulthood.
The most noticeable symptom when a person has eczema is the rash. This rash can appear anywhere, but it does seem to be most prominent on the neck and behind the knees and the elbows. This rash may not be extremely painful, but it can most definitely be uncomfortable. There are many over-the-counter medications that can be applied to the rash, and a medical professional can also prescribe something of greater strength. The rashes typically consist of small, red bumps, and they can cover a small area, or they can even cover many different areas of the body.
