oooo perfumed bath bombs are a definte cause for thrush - you dont need to have discharge to have thrush - the itch says it all - I wouldnt use sudocrem on there though - canestan duo cream 2% is what you need - plus the tablet pessary you put up the vagina is the best treatment, works within 1-2 days, but you will feel a difference in 24 hours
. If it does not get better in 5 days or you get a rash etc go to the Dr as could be a skin condition (but I think its thrush) x
Its horrible so good luck
