My 7 y/o 56lb son has sore throat, stomach, & chest pain, fever. Has asthma. Gave br. Teatment, made fever break. What causes these sx? Allergic 2 flu shot

Mgt. I would suggest having a flu test to confirm influenza. I would advise a course of anti influenza medication, since he may have the flu. Asthmatics are prone to worsening with this viral illness. If the breathing treatments are not helping a course of steroids may be used.
