Hi i am Dr Ahmed Aly thanks for using HealthcareMagic site , I had gone through your question and understand your concerns .. In my opinion that is a kind of allergic interaction , try to apply topical anti-histamine ointments and ice padding 2 or three times a day . elevation will help your swelling to go down so try to avoid standing for a long period of time . anti-histamine systemic tabs like zyrtec may be needed to decrease your body reaction towards that bites . If the swelling persists and signs didn t fade away i recommend you visit your physician for proper evaluation and management because 2 weeks is a bit too long for an allergic reaction . Please click and consider a 5 star rating with some positive feedback if the information was helpful. Wish you good health, Any further clarifications feel free to ask.
