I am so sorry you are dealing with these persistent, frustrating throat infections. Since strong antibiotics like moxifloxacin, amoxicillin-clavulanate, and linezolid haven't cleared this up, we should look beyond typical bacterial infections. I highly recommend seeing an Ear, Nose, and Throat (ENT) specialist. They can perform a detailed exam, possibly using a small camera to look closely at your throat, and take specialized cultures to check for fungal or resistant organisms. We should also investigate non-infectious causes like silent acid reflux, allergies, or immune system health. There are many effective management options, sometimes including tonsillectomy, and we will work to find you lasting relief.

Since it has only been three weeks, you can start using topical treatments like Mederma or silicone-based gels, provided all scabs have completely fallen off and the wounds are fully closed. Applying a broad-spectrum sunscreen daily is also essential to prevent the scars from darkening. For advanced clinical options like laser resurfacing or microneedling, it is best to wait at least six months to allow your skin to mature naturally. A dermatologist can help guide you when your skin is ready.

Since fexofenadine (Allegra) hasn't provided relief, these symptoms?particularly worsening at night with blistering?highly suggest a skin condition like scabies, which can sometimes be linked to pet exposure. I recommend seeing a doctor or dermatologist for a physical exam and a quick skin scraping to confirm. If confirmed, the standard treatment involves prescription topical permethrin cream or oral medication, as antihistamines won't cure the underlying cause. It is also important that all household members are treated simultaneously, and bedding is washed in hot water.

While a hard, painless neck lump should be evaluated by a doctor to rule out serious conditions like lymphoma, there are many common, benign causes. Your chronic allergies and post-nasal drip, which you treat with Allegra (fexofenadine) and nasal spray, can cause lymph nodes to swell in response to inflammation. Additionally, the tender lumps on your back are often harmless cysts or localized skin infections. Please schedule an appointment with a healthcare professional soon for a physical exam to give you accurate answers and peace of mind.

It is very common to have questions about your medication. Taking Allegra (fexofenadine) daily for more than a week can sometimes cause mild throat-related side effects, most commonly throat dryness. This dryness can occasionally lead to a slight tickle, mild irritation, or a dry cough. This happens because antihistamines work by drying up fluids to relieve allergy symptoms. Please be reassured that this is a very common, harmless side effect. Staying well-hydrated by sipping water throughout the day or using throat lozenges can easily help soothe this. If you feel any severe discomfort, do check in with your doctor.

Allegra (fexofenadine) is a daily medication that typically wears off within 24 hours. Once the medicine leaves your system, the itching returns because the underlying cause of your reaction is still active. Since the itching is severe and keeps coming back, I highly recommend scheduling an appointment with your doctor or an allergist. They can help identify the root cause, safely adjust your daily dose of fexofenadine, or recommend other targeted treatments to give you lasting relief.
