Chronic urticaria and Cough for the past 4 yrs - #11347
21 yr old female facing this problem from more 4 years sometimes I am completely fine but sometimes I face a lot of this. Case Summary: Recurrent Urticaria with Intermittent Cough Chief Concerns Recurrent skin welts/rashes and itching, often appearing after bathing or where clothing rubs/presses. Intermittent cough Both skin rash and cough episodes improve with cetirizine. Pattern & Triggers (Patient-Reported) Skin: Raised red lines/welts where clothes press or scratch → consistent with dermographism/pressure urticaria. Rashes sometimes after bathing and on hot days or mild exercise → suggests cholinergic (heat/sweat) urticaria. Episodes last hours to a day; swelling/itch varies; respond reliably to cetirizine. Cough: Occurs in phases; often with throat or nasal irritation. Improves with cetirizine, suggesting histamine-mediated mechanism (allergic rhinitis/post-nasal drip). Relief noted: Cetirizine helps both cough and rash. Moisturizer helps itch. Possible aggravators: Dust at home, bathing, clothing pressure, heat/sweat. Past/Relevant Data Total IgE: 163.7 (mildly elevated) → consistent with allergic tendency. Vitamin D: Previously 18 ng/mL (deficient). Lifestyle: Vegetarian, sedentary, >8 h sleep, no known chronic diseases. Medications tried: Cetirizine PRN, occasional cough syrup. Symptom Behavior Cough and rashes appear in an alternating pattern: when one flares, the other subsides. Both improve with cetirizine, but recur once the effect wears off. Current Concern Despite temporary relief with cetirizine, symptoms recur repeatedly. I want to understand the underlying cause of this alternating pattern of cough and rashes, and why antihistamines are the only thing that consistentlly working on this?
