Hi, my 11 year old seems to have the chicken pox. She has appox. 10-15 chichen pox right now. This is day 2, she noticed yesterday a hard pea sized lump between the middle of right ear and bottom center of head.(hairline)  It is sore when touched. Today she has one more not quit as large, about a half inch above the other. Neither of these look like a chickenpox? Any idea?
From what you have told, your son may have two enlarged lymph nodes. Lymph nodes are small pea shaped lumps present all over body. It gets enlarged and painful when infection is there. Many a times chicken pox will not cause any lymph node enlargement. But Since his immunity is weak now, a bacterial infection may set in and may have caused the lymph node enlargement.It's better to wait and watch. If the Lymph node does not subside on its own, a course of antibiotic may be given.In the meantime give plenty of water and paracetamol tablets to reduce fever.
