Cold and sweet foods can trigger a reflex that temporarily narrows your airways and increases mucus, especially if you have sensitive lungs. Regarding your previous medicines, Allegra M (fexofenadine and montelukast) helps control allergies and airway swelling, while Aerodil syrup (containing terbutaline and mucolytics) works to relax airways and thin mucus. While these medications target your symptoms, wheezing and tight breathing can escalate quickly. It is safest to avoid reusing old prescriptions without a doctor's evaluation, as you may need a different preventive treatment. Please consult a healthcare professional to ensure you get the safest, most effective care.

Since you are already taking Allegra (fexofenadine) and practicing yoga, you are on a great path. To build on this, consider using dust-mite-proof covers on your bedding, using a HEPA air purifier, and doing daily saline nasal rinses to clear out allergens. For a long-term solution, you might discuss allergen immunotherapy (allergy shots) with an allergist, which can train your immune system to be less sensitive over time.

It is generally safe for your wife to receive the COVID-19 vaccine. Having rheumatoid arthritis and taking levothyroxine (Thyrocare) are not contraindications. Her past severe reaction to the antibiotic nitrofurantoin does not increase her risk, as vaccine ingredients are entirely different. However, she should inform the vaccination staff so they can monitor her for 30 minutes post-vaccine as a precaution. You do not need to keep steroid medications on hand; any rare, immediate allergic reaction is safest and most effectively managed by the trained medical team on-site. I highly recommend discussing her current health status with her doctor before scheduling her shot.

Recovering from COVID-19 can sometimes leave your immune system temporarily reactive. It is reassuring that fexofenadine (Allegra) helped your rash; you can continue taking this antihistamine daily under medical guidance. For the fluid-filled bump on your forehead, please avoid squeezing it and keep it clean. For your painful, receding gums, warm salt water rinses and gentle brushing will help soothe the area. Because these symptoms affect different systems, I highly recommend having a doctor evaluate the forehead bump and rash, and a dentist examine your gums to ensure you receive the correct targeted treatments.

Eardrums are delicate and heal by growing new tissue, which can naturally take several weeks to a few months, even without an infection. While your allergy medication, Allegra (fexofenadine), is helpful for keeping ear pressure stable by reducing nasal congestion, it doesn't directly speed up tissue repair. Healing time often depends on the size of the tear and keeping the ear completely dry. Please protect your ear from water and continue monitoring it with your doctor to ensure it heals safely.

Since fexofenadine (Allegra) did not help, you can safely try non-medicinal relief. Applying cool compresses or taking a lukewarm oatmeal bath can soothe the itching. For topical relief, a mild hydrocortisone cream is generally safe to use while breastfeeding, just ensure it is not applied near the breast area where your baby could contact or ingest it. Because your rash is severe and did not respond to the antihistamine, please consult a healthcare provider promptly to safely diagnose and treat the underlying cause.
