Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. It is most likely that what you are feeling are lymph nodes. The location you describe is a common place to feel them. Normally, people have them all over inside their body. Usually, they are too small to feel. If there is a scratch, burn, or infection then the nearby lymph nodes will react and enlarge and can be felt. You may check her scalp to see if there is any scaling, red areas, or bumps with pus. If so, then that might explain the enlargements you feel. If your baby is otherwise healthy and you cannot feel any others, then probably nothing needs to be done now except to watch. Other parts of the body where lymph nodes are in front of neck, underarms, in the groin creases. If she develops fever, loses weight, or you feel more lymph nodes, then take her to the doctor right away. I suggest that you take pictures of them now so you can compare the pictures with how they look later on. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Arnold Zedd
