My 8 month old son has a strange nipple on the left side. It looks like it's erect and is white it almost looks like you could squeeze it kind of like a spot. If you rub it you can feel a lump will take him to see hv next week, but was wondering if anyone has any ideas what it could be, was wondering some kind of cyst has been like that for a couple of months but has become more pronounced recently. Doesn't cause him any pain but my mum saw it and has worried me now by saying he needs to see someone that's not normal!
