Chronic nasal congestion often leads to mouth breathing, which can cause saliva to pool and look like frothing at night. The nasal redness is likely from rubbing. The abdominal pain could be a mild reaction to Allegra (fexofenadine) or Sinarest, particularly if taken without enough food, or from swallowing excess mucus. Please keep him hydrated and comfortable. I highly recommend visiting his pediatrician to safely investigate these symptoms and review his medicines.

Allegra is currently keeping your symptoms under control. While there is no immediate 'permanent cure' for chronic hives, the good news is that they often resolve on their own over time. For a long-term solution, I highly recommend consulting an allergist or dermatologist. They can help identify underlying triggers and discuss advanced, targeted treatments to help you achieve lasting remission.

To help ease the pressure in your ears, a warm compress and nasal saline sprays can be very helpful. For the sore throat, warm saltwater gargles and staying well-hydrated work wonders. Over-the-counter pain relievers like paracetamol or ibuprofen can reduce discomfort. Since these symptoms are recurrent, it is highly recommended to see a healthcare professional. They can check for underlying causes like allergies or a sinus infection and guide you toward a lasting solution.

Since your symptoms return quickly after stopping deflazacort and fexofenadine, it is important to find a safer, long-term solution. Prolonged steroid use can have side effects. Under a specialist's guidance, next steps often involve increasing your daily non-drowsy antihistamine (like fexofenadine) up to four times the standard dose. If this is still ineffective, advanced therapies such as a targeted biologic injection (omalizumab) or other immunomodulating medications can be highly effective. Please consult an allergist or dermatologist to safely transition off the steroid and find a personalized treatment plan.

Since you are already taking Allegra (fexofenadine) alongside your antibiotics, MOX-CV (amoxicillin/clavulanate) and Kind 600, these new symptoms could be a mild allergic response or a simple viral cold. Please do not stop your antibiotics. I highly recommend contacting your prescribing doctor to report these symptoms. They can safely evaluate if any adjustments to your medication are needed. In the meantime, rest well and stay hydrated.

Red rashes and itching that appear after a fever and body pain may indicate an infection, an allergic reaction, or a viral illness. You should consult a doctor immediately for proper evaluation and treatment to prevent complications.
