Both of us have the history of sensitive nose and unfortunately the kids inherit the problem too. Janelle is still better, however she gets dry and itchy eyes pretty often. Julian case is slightly serious, we always heard him sneezing early in the morning or even before he went into deep sleep. These nights were worse, poor Julian having very blocked nose that is affecting his sleep. It got serious that he ended up with swollen nose, nasal blockage that cause it. Law decided to bring him to Dr Sim for a solution. He need to take Clarinase for a period of time, as the effect last long. Zytrec medi effect only kick in two hrs after taking. By 2hrs, he nose is very badly blocked. Every morning, Julian has to apply the nasal spray and this has to continue for 3 months to see if he is getting better. SO far the result is good, I did not see him sneezing away anymore. Julian swollen eyes Medicine from PD Sim.
