hi my son age 10 has a lump on the back of his neck, complained of head feeling puffy, couple days later found lump behind right ear, was treated with antibiotics although dr. did not think it looked like infection and no accompaniing symptoms like red or hot, no fever and no change after, day 10 now lump is changing color and starting to go purple, no pain, no cold symptoms. Complains of pin and needles in head or fuzzy feeling, no energy, fainted or calapsed the other day, and is getting headackes. Says he just does not feel right, Blood work normal. What to do?
