Hello, and I hope I can help you today. First of all, I want to assure you that an allergic reaction would not just produce itching in your vagina. Allergic reactions typically cause itching and rash all over the body, so I really do feel confidently that your symptoms have nothing to do with eating eggs. Vaginal itching is most commonly caused by a vaginal infection with Candida, otherwise known as a vaginal yeast infection. Vaginal yeast infections are so common that in most countries, treatment is available for purchase over-the-counter in pharmacies. If you have never had vaginal itching before, it would not be unreasonable to go for an examination by a gynecologist or women s healthcare provider to confirm the diagnosis. The irritation of the vagina from the infection can cause burning with urination as well, however if there is also infection of the bladder, antibiotics are necessary for treatment which can only be acquired through a doctors prescription. The medication to treat a vaginal yeast infection is typically an antifungal cream or suppository that is inserted into the vagina typically for 3 to 7 days. The active ingredient in the medication should have the ending -azole, for example: miconazole nitrate, fluconazole, or clotrimazole. Using these treatments according to package directions should result in complete relief by seven days. If you try the yeast infection product and it does not work, I strongly recommend you visit a physician for examination of your vagina and analysis of your urine, as you may have a type of infection that is not treatable with over-the-counter medications. I hope I was able to adequately answer your question today, and that my advice was helpful. Best wishes, Dr. Brown
