<s>[INST] Hi my 4 yo son started having puffy eyes and some congestion. He has a rash around his eyes that I thought came from rubbing but now the rash has spread to his chin, his torso and now his extremities. He was in our pollen filled yard in freshly cut grass. I have kept him inside and given him zyrtec but the syptoms has gotten worse. He doesn't have a fever and is still very active any clues? [/INST] seems to be allergic for which you already given zyrtec. if no improvement tell me the type of rash itchy or not and time since zyrtec is given </s>
