Hi I am suffering from chronic urticaria from past 3 years. I am using teczine 5mg tablet when the itching and burning is behind controllable. I also tried Ayurveda (Patanjali) medicines for one month but the allergy which was stopped again started coming. I don't know what to-do. When the allergy is at peak.. My chest tightens and I'm not able to burp.. Once the burp comes it pains in middle of my chest as if it's some needle is pierced in my centre chest.. Can someone tell me a real cure for this allergy. With teczine tablet I'm feeling way too drowsy were I cannot even open my eyes. Please help me Thank you so much!!
