Eczema is not painful, some eczema is mainly rough and flaky, sometimes even cracked in severe cases. This eczema becomes a long term chronic process that lasts for years and years and does not recede and is not painful or itchy. This manifestation is dry eczema. Dry eczema is actually caused by inflammation associated with excessively dry and flaky skin, and the flakes that are shed irritate the skin. Also, because dry skin lacks a sebaceous film, it lacks a protective film against external stimuli, making it easier for external stimuli and allergens to enter the skin and cause inflammation. However, this inflammation is only manifested by the above-mentioned rash, but it can be painless and itch-free.
