Presence of sore neck with headache is usually due to an infective cause.
The lump can be due to enlarged lymph nodes in response to the infection.
Symptomatic relief from pain can be obtained with the help of analgesic
& anti inflammatory preparations.
The infection can be controlled with the help of antibiotics.
However, if symptoms persist or associated with high fever
, disturbance in vision, loss of consciousness
, convulsions, etc. then immediately seek medical attention.
Wishing your child a Good Health.
Thanks & take care.
