Brief Answer:
Yes excessive cough can cause sweating

Detailed Answer:
Hello

Ear and sinus infection can be viral or bacterial in origin.In children viral infection is much more common than bacterial and it usually involves ear,upper airway and sinuses simultaneously.Cough may be due to irritation of upper airway or spasm of airway. Both of these can occur in viral respiratory infection.

Sweating is usually associated with fever but there are so many other causes of sweating. Excessive cough can cause sweating just like sweating during exercise.As he has been diagnosed with sinus and ear infection it appears to be due to cough.

So no need to worry much.As some of the medication used in cough for relieve of bronchospasm may cause sweating.Consult your physician to rule out other possibilities and discuss with him/her the condition.
