What are safe options to deal with red bumps without knowing what caused it? (photo)

Hi, Thank you for your question and pictures. From the photos and in the absence of any history provided, these tiny bumps appear to look like closed comedones (commonly known as "whiteheads"). Some could also be milia, and less likely, syringoma. A doctor will need to ask you more questions such as whether these bumps are itchy/painful, whether you are on any oral or topical medications, your current skincare regime etc to be able to diagnose and manage this most appropriately. Comedonal acne and milia respond well to non-invasive treatment such as medical-grade vitamin A derivative creams.

Hi,Perhaps the splinter is still inside. Could you head to the nearest emergency or family doctor as soon as possible to try to remove it? Usually what I would do is to numb the area, then gently scrape it with a sharp blade. Or sometimes I don't numb it, so that the patient can feel if the thing is still inside.
