Hi. I'm Dr. Lee and will do my best to help.
Can you tell me are there any other lymph nodes that are enlarged aside from the ones near the neck?
Also, does she have a fever? And is she still eating and drinking normally? And otherwise doing well?
It appears that you are unavailable at the moment. If you can please provide the information above so I can better understand the situation and help. Once you reply, I will return to this chat as soon as I can. Thanks!
