My 7 month old son has had one red pimple like spot on his cheek for about 6 weeks now. It has no white head but is slightly inflamed and hard on the top.  It is about the size of a pin head and seems to give no pain or irritation.  Does it need treating or will it go away eventually?
Hi.by what you quote I feel that it could be a prolonged fungal infection or an eczema with secondary infection. But, skin conditions are best diagnosed only after seeing directly. I suggest you to upload photographs of the same on this website, so that I can guide you scientifically. Hope my answer was helpful for you.  I am happy to help any time.
