my 26 month old daughter has had a white head on the outside of her left arm since mid-september. a couple people (including her pediatrician) told me it s probably from a bug bite and it will go away. however, it has been popped (on it s own) 3 times but keeps recurring. she constantly says it s hurts and cries if i even try to just look at it... should i be worried?
Hi...by what you quote I feel that it could be viral wart especially as it is recurring. You can use Selection lotion (salicylic acid) for it. 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. Further clarifications and consultations on Chat Doctor are welcome.
