Severe itching from Urticaria can be very uncomfortable and is usually due to an allergic reaction. You can take an antihistamine like Cetirizine for relief, apply soothing lotions, and avoid known triggers like certain foods, heat, or stress. Wear loose clothing and keep the skin cool. If the rash is persistent, severe, or associated with swelling of lips/face or breathing difficulty, seek medical care immediately.

Often, when allergies (treated with fexofenadine) or infections (treated with azithromycin) aren't the cause, chronic irritation from silent acid reflux is the culprit. An Ear, Nose, and Throat (ENT) specialist can perform a simple test called a flexible laryngoscopy to look closely at your throat. They might suggest managing possible reflux with lifestyle adjustments or generic acid-reducers like omeprazole. With the right treatment to stop the underlying irritation, these tissues can absolutely shrink and disappear completely over time.

It is very common for children to have a lingering cough and mild sore throat after recovering from COVID-19. Since your son is already taking Allegra (fexofenadine) and Zincovit, please continue these as prescribed by his doctor. To help soothe his airway and ease the nighttime cough, keep him well-hydrated with warm fluids and use a cool-mist humidifier in his room. Elevating his head slightly while sleeping can also provide comfort. If his cough worsens, or if he develops a high fever or breathing difficulties, please consult his pediatrician promptly.

Sometimes, an underlying skin condition can also worsen independently. Because her redness, itching, and burning have spread across her entire body, she should stop taking fexofenadine and contact her doctor or seek medical evaluation right away to stay safe. Please reassure her that a healthcare provider can help identify the cause and find a safer, comfortable alternative for her. If she develops any trouble breathing, throat tightness, or facial swelling, please seek emergency medical care immediately.

Since your symptoms resolve with fasting but return when you stop antihistamines like hydroxyzine, levocetirizine, or fexofenadine, we should consider conditions like chronic spontaneous urticaria, a specific food allergy, or histamine intolerance. I reassure you that we can manage this. I highly recommend keeping a detailed food and symptom diary and consulting an allergist or immunologist. They can safely guide you through a supervised elimination diet and help you find a long-term management plan so you don't have to rely solely on daily antihistamines.

His severe leg itching could be caused by dry skin (xerosis), which is common in diabetes and can be worsened by infrequent bathing. Since Allegra is not providing relief, the itching may also stem from diabetic neuropathy (nerve irritation) or poor circulation in his lower legs. I gently recommend keeping his legs clean and applying a thick, fragrance-free moisturizing cream daily. Please consult his doctor to examine his legs and check his blood sugar levels to rule out any underlying infections or nerve issues, ensuring he stays comfortable.
