Hi. My 3 year old son has a red, swollen, Hot heliex that I have JUST noticed. The entire helix, from top to bottom is swollen to roughly 4-5 times the normal size. Also, he has a bump behind his ear lobe about the size of a big pea that s NOT hot or red. He seems to have tiny pink bumps around his mouth that developed roughly 5 hours ago. There are NO apparent bug bites anywhere on his body,NO knowb allergies besides pennicilin and No family history of other allergies or diseases. Does this sound like an allergy? Infection? Disease? Hypothetically, if u had a patient with these symptoms, would u send them to the ER, your office in the morning, or to the drug store for something over-the-counter? Thank you in advance.
