Was dignosed with chicken pox 5 days ago, i am really extremely itchy vagina. should i be worried? is there something i can use?

Not particularly: Unfortunately the adult form of the disease is often worse than in kids. The sores can emerge in & around the mouth anus and genital skin. The itching is aggravated by the salt in your swear & as such frequent rinsing of the area with plain water provides some relief. Cold compresses in troublesome areas also help. A mild hydrocortisone cream (1/2-1%) can help. Keeping it clean can avoid infection
