Thank you all.First of all correction in reply posted on 30.09 2000—It is COLD not OLD.
Some points may be relevent are—We got CT SCAN for PNS of my son.As per findings my son is having “Deviated nasal septum with convexity towards right and B/L nasal turbinal hypertrophy , both maxillary,ethmodal frontal & sphenoidal sinuses are displaying normal aeration without any intrasinosal mucosal thickening or air fluid level” Could this be a factor of my son’s sneezing problem.I have notice such problem is common in other children of this our area.About 10 %to 20% are suffering from such sneezing problem,even some middle age persons who have migrated to this locality have also developed this .So I am afraid that even by clinical correction of septum will help my son .

My son is little bit introward (not too much) .He likes sweets. ( during fever his feet have very low teperature than his whole body) He is submissive in nature but opposes even right things initially.
Strong built with slightly over weight. Likes to play games specially badminton.
He feels hot all the times and prefer to be in air conditioner.
