Depending on your age, there are many causes to vaginal itching and redness as well as dryness. Also, I would have to know whether there was any secretions associated with your symptoms. So, important questions would have to known including your age, sexual activity, gynecological history, menstrual history and any changes in home poroducts including detergents, soaps perfumes. Once this information is obtained then a gynecological examination would have to be performed with the acquistion of specimens during the exam.
Thank you for the question.
