Why do I develop numerous painless, itchy little red spots on my body sides after taking a bath?

After taking a bath, many small red spots that are neither painful nor itchy may appear on both sides of the body. These could be caused by unsuitable water temperature, excessive scrubbing, allergic factors, among other reasons. Treatment can be provided through general measures and medication based on the underlying cause. Specific explanations are as follows:

1. Unsuitable Water Temperature:

When the water temperature during bathing is too high, it can irritate the skin, causing dilation of the capillaries in the skin and the appearance of red bumps that are neither painful nor itchy. It is not recommended to bathe in excessively hot water.

2. Excessive Scrubbing:

Scrubbing excessively during bathing can lead to the appearance of red bumps on the skin. Avoid over-scrubbing the skin during daily bathing.

3. Allergic Factors:

People with allergic constitutions may have allergic reactions to body wash, soap, etc., manifested as skin rashes or red spots that are neither painful nor itchy. Medications such as cetirizine tablets or loratadine tablets can be administered, and further contact with the allergens should be avoided.

Skin infections and allergic purpura can also present with the above symptoms. It is recommended that patients identify the underlying cause before receiving targeted treatment.
