Dear enquirer It appears your son is atopic child. The
eczema asthma
hay fever those are
allied conditions. I think you are doing right giving him
zyrtec and
bronchodilator medication
through nebuliser.The painful protuding movable lump which you described are inflamed neck
glands. I think iyou should take him to your doctor who may give him antibiotics, that will settled
soon. Kindest regards S.K.Mukherjee
