My eight year old son has about ten little red spots on his back all clustered together some with yellow heads, he also has one on his knee and a couple elsewhere, he does not feel poorly and is generally well, just wondered what they might be, thank you.
Thanks for posting your query at Chat Doctor. The information is not enough. But still, I would try to answer. The red marks could either be infected boils which are caused due to certain bacteria or viruses, or they could be simple petechial/purpuric spots (small bleeding spots) but in that case they are unlikely to have a yellow top. Information on whether there is associated fever would have been helpful. It is hard to comment further without looking at them and without knowing whether they are itchy. You may apply calamine lotion over the area should help. Please revert with further information and I would try to help further.
