Swelling after a bee sting is common and usually due to a local allergic reaction. Apply a cold compress and keep the affected area clean to help reduce swelling and pain. Avoid scratching or pressing the area, as it may worsen irritation. Seek medical care immediately if swelling spreads, becomes severe, or if you develop breathing difficulty.

Since oral itraconazole and antihistamines weren't effective, the next best step is seeing a dermatologist. They can perform a skin scraping, culture, or biopsy to check for bacterial infections, atypical yeasts, or inflammatory conditions like inverse psoriasis. For relief, they might suggest drying solutions (like aluminum acetate), topical mild steroid creams, or non-steroidal anti-inflammatory topicals.

Since your ear pain, itching, and hearing issues persist despite using Otobiotic, Soliwax, Allegra, and Saffrone-P, it is very important to have your ear re-examined by your ENT specialist. Sometimes, a persistent outer ear infection, a fungal issue, or fluid behind the eardrum requires a different treatment approach. In the meantime, please keep your ear completely dry while bathing and avoid inserting anything, like cotton swabs, into the ear canal. Your doctor will look closely inside to find the exact cause and safely adjust your treatment so you can find relief.

Since antihistamines and antifungals haven't helped, a key consideration is scabies, a very common and highly treatable skin condition caused by tiny mites. Other possibilities include contact dermatitis or a viral rash. I highly recommend visiting a healthcare provider for a physical exam. If it is scabies, they can prescribe highly effective targeted treatments, such as topical permethrin cream or oral ivermectin. Washing your clothes and bedding in hot water will also help clear it.

Please be reassured that there are many effective alternative paths. Since these oral medications haven't cleared the allergy, your doctor might recommend adding a mild topical corticosteroid cream to soothe the skin directly, or performing allergy testing to pinpoint specific triggers. In some cases, a short course of oral corticosteroids or alternative non-steroidal therapies may be suggested. I highly recommend consulting your doctor or a dermatologist to safely adjust your treatment plan.

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.
