Ihave recently gone to the beach for a whole so I was in and out of the water all day in my bathing suit. Before I left I made sure to rinse off a bit, changed my clothes even though i had a tiny bit of sand left on. I tried getting off what I could. After my 2and a half hour trip I was fine took a shower and the next morning I started to feel very itchy and burning on the outside of my vaginal area and with now improvement throughout the day. Is there anything that could help this ?
