While washing up today, I noticed some small red spots on my arm. They don’t cause significant discomfort, but feel slightly itchy when touched. Could you please advise what might be causing this?

Hello, the appearance of small red spots on your body could be due to various conditions, such as allergic dermatitis, folliculitis, purpura, or angiomas—there are several possible causes. If the red spots are accompanied by itching, allergic dermatitis is more likely. If they are painless and non-itchy and blanch upon pressure, this suggests a subcutaneous hyperemic change, making an angioma the most probable diagnosis. If the condition is allergy-related, it’s essential to avoid known allergens during this period to prevent recurrence. Avoid vigorous scratching to reduce the risk of infection. We hope this information is helpful. Wishing you good health!
