I have a minute spot on my perineum which nevertheless seems to get very sore after I have done a lot of cycling. When I say "minute", I mean you can barely see or feel it, and most of the time I don't even notice that it is there. I first noticed the irritation last summer, but then the problem seemed to die down over the winter - possibly because of the colder weather or because I was doing less cycling. But it seems to be flaring up again just as I am about to go off on a four day tour. I don't suffer from saddle soreness generally, apart from this one small area, so I don't think changing shorts or saddle would necessarily help. Any ideas?
