Hi there
I know this may seem strange but maybe get your gallbladder checked out if it continues and it's not thrush. Around a month or so before my gallbladder problems kicked off I developed a very itchy behind and it continued all the time until I had the blighter out, once it was gone the itchiness went! During this time I did read somewhere it can be a symptom. Yours maybe totally unrelated but if it persists maybe worth bringing up with your doc.
Or it maybe sitting and getting a bit warm in that area which is leading to the uncomfortableness? We shouldn't sit for too long, we can develop sores which can get quite nasty if left untreated, mainly happens to guys but I've heard of it twice now of guys who sit at computers all day.
Hope it clears soon and you get some relief.
