I have had itching it feels like on a patch inside my vagina near the entrance. I have tried pessary and oral thrush tablets and creams but it's not gone away. I've had a good look several times with my torch and mirror and cannot see any lumps, spots, bumps etc. I am at a loss what this would be? It's not a constant itch and some days it's worse than others. Sometimes I think it's gone then it seems to come back! Any idea what this could be? I am 43 and on the pill
