I understand your concern, though the allergy is cured by antihistamines and local applications there are always chances of recurrence, so you should avoid the allegen

Yes, allergy can be cured. But not just with medicines. In modern medicine, Antihistamines is the preferred drug of choice in management of allergy. But there are some life style modifications by adopting which we can get better. 1. Do some regular exercise. Can be anything walking, jogging, gym, yoga, anything preferred to you. (Lung volume should be expanded, due to sedentary life style your lung volume and breathing pattern should probably be puny) 2. Ensure good night sleep. 3. Take more of pepper, tulsi, Ginger, Garlic, betel leaf. ( Helps in increasin inner heat in body) Chillness leads to vasoconstriction, which is the reason your extremities and ears get chilled out on Ac. It is bodies responce, not a disease. If you still don't get my point, get back to me in a private chat/ phone consultation.
