ALLERGIES! I've seen it before many times. I have a wonderful allergist and she specializes in pediatrics as well. Your baby will not have to be tested for allergies immediately or something like that.
First the doctor will to an exam of the ears, nose and throat. She can see when I am inflamed and am having an allergy reaction by the color of the wall inside my nose and many standard doctors have not been able to diagnose this - only my allergist. She's very experienced.
Same with both of my children. She can tell when the area below the ear (deep inside the ear) seems swollen just by touching the spot. I now take the kids in almost every time they have anything upper respiratory as it all starts with their allergies and the doctor is so skilled at seeing it I wouldn't take them anywhere else. As an indication of this - - I've taken them to the pediatrician for bronchitis symptoms before and the meds they gave made the kids worse instead of better. Taking the kids to Dr. Arora has meant a clear up in a couple days. She understands the right medicines to give and the right treatments for upper respiratory. She's a Godsend.
Bottom line - she has saved our lives. I couldn't live without her.
Please contact her!!! My allergist's name is Dr. Nirmala Arora. She is located at Good Samaritan's Doctor building. She's also got an office in Bolingbrook.

Best of luck,
