Introduction

Under normal circumstances, itchy palms may be caused by contact dermatitis, but could also result from other skin conditions or diseases. Whether it is contact dermatitis needs to be determined based on specific symptoms and causes. If discomfort occurs, it is recommended to seek timely medical consultation and treatment at a正规 hospital. When experiencing itchy palms, avoid further contact with suspected allergens, do not wash with hot water, and refrain from excessive scratching.

Generally, palm itching may be contact dermatitis, but it could also be caused by other skin conditions or diseases. Whether it belongs to contact dermatitis needs to be determined based on specific symptoms and causes. If discomfort symptoms occur, it is recommended to seek timely medical treatment at a regular hospital. Detailed analysis is as follows:

If there is a clear history of contact before the palm itching, such as contact with allergenic substances like detergents, metal accessories, cosmetics, etc., and there are clearly demarcated red patches, papules in the itchy area, and severe cases may be accompanied by blisters and exudation, with symptoms appearing shortly after contact and subsiding gradually after removal from the contact substance with appropriate treatment, then it may belong to contact dermatitis. This is an inflammatory reaction occurring at the contact site after the skin or mucous membrane comes in contact with exogenous substances, and itching is one of its common symptoms.

If there is no obvious contact history for palm itching, or when itching occurs the skin appears diffusely reddened, dry and peeling, and symptoms recur related to seasonal changes, emotional fluctuations, rather than being triggered by contact with specific substances, then it usually does not belong to contact dermatitis. It is more likely to be other skin diseases such as eczema, dyshidrosis, hand fungus, or caused by nervous system dysfunction.

When palm itching occurs, avoid recontact with suspected allergens, do not wash with hot water or scratch excessively to prevent worsening symptoms. You can first rinse your hands with clean water and observe the changes in symptoms.
