Hi maam,    My son virat, regularly have cold problem and other relevant problems like itchy nose, rubbing eyes and itching problem in the fold areas like down to neck, under the penis part, behind the knee areas, itchy scalp, especially when oil is applied.I have been using homeopathy medicines from homeo mall near to my home, but there's no result...so, recently I visited rainbow hospital, they have given few medications,  if I don't use them one day also, itching will be more... I have consulted many allopathic doctors, but no result...I have his blood test report of 9 months back, where the result shows like eosinophills count is high...
