Suggest Remedy For Swelling In Forehead With Rashes In Face

My 3 yr old son has a swollen lower forehead, that moves down his bridge and ontotheleft side of his nose. He also has a rash, red and bumpy, not like pimples on his forehead on his face and now going to his neck and chest. There is no fever and the pressure doesn't seem to bother him, also he hasn't bumped it at all I doubled checked with his daycare as well. He has little appetite and a bit tired. He does get frequent ear infections but this is not the same,and he tells me when his ears are hurting.
