question: Hi Doctor, I need a suggestion on Allergy.I have got Itchy and burning sensation of Allergy.But i have found out the combination of causes.  I have got allergy reaction so far 2 times.But they are having few common reasons.I had allergy when i had the below things.1) had Constipation or gastric trouble2) had Brinjal in Lunch3) had Tender Coconut Water4) after that i had PAD - D tabletI am confused which is the exact reason for my allergy.I have planned to avoid the Brinjal in my food.But i felt fine having Tender Coconut water earlier but not with the above combinations.(i mean i had Tender Coconut water alone not with brinjal and Pan - d).I request you to provide the advise on this.
