HI I have gone through your mail and as you said your younger child of one year of age has got high grade fever with redness
of face and neck lymphnodes
below the ear both sides. After considering your complaints I wants to consider about mumps in your child also, so please go for ultrasonography
of parotid area (area anterior and just below the pinna of ear) and also F.N.A.C. of neck swelling.You should also consult physician to look for koplic's spot on buccal mucosa and clinical co-relation with investigations to establish diagnosis and treatment.Thanks.
