Its possible that is what it is cause I believe itchiness is a symptom, if your embarrassed to go see a doctor you could get a test at the store (if you can afford it) that you can get without a prescription at the store. If it shows you have one, that is when you should go see your doctor and don't go just cause your embarrassed try and think of something positive to get you through the appointment. I always think when I go for something embarrassing I just think, its for me and it will make me better. Not getting help and making things worse will just make you more sick. Its okay to seek help. Good Luck!
