Sinus infections may result from prolonged colds. A sinus infection should be suspected if:
- the cold lasts longer than 2 weeks
- a fever of greater than 100.5F or greater occurs for three days or more as part of the cold.
- your child has had a cold for several days and then starts complaining of a headache under the eyebrows or in the cheekbones. It is common to have a headache and body ache the first few days of a cold.
- it is normal for mucous to be either clear or colored (yellow or green) at various times during the cold. Yellow or green mucous is not a sign of a sinus infection.
- young children get colds frequently. Children under three get an average of 6 to 10 colds a year each lasting for 1 to 2 weeks.
