HI , DR. Sumit , I would like to ask about a case of my cousin , she is a female 20 years old , she suffers from throat sensitivity to cold drinks to the extent that she can`t drink cold drinks at all even in the summer which is really a suffering thing for her , cold things make her get infections and kinds of sore throat , i asked a doctor before and he told me that she should make an IGE serum test ... I am asking for ur sincerely advice about that test and if this case can get improved by treatment or it is a chronic case can`t be treated or relieved ??? ... thanks DR. SUMIT
