My son is 15m old at 4m he started getting 2 quarter six lumps in his head that come and go as they please I have been to multiple of doctors that say it s hives to keep a good normal I have its not from anything particular that he eats they keep putting him on allergy meds but it does nothing I m looking for another opinion they only last a day when they come then go away then come back another day I m sick of being told its hives it s only on his forehead what could it be they are red and the size of a quarter always in the same 2 spots his doctors today said normally hives wouldn t be on the forehead so she was gonna do some more thinking on it but to give him clariten for 2 months
