I have been having these syptoms off and on for years now and it is very frusterating the first syptom is a itchy anus not a slight itch but you have to sit down or rest and if you try to scratch it my ears pop or sometimes if the itching is very bad the ears pop by themselves how these two are connected I do not know, now i have a itchy uretha it does not hurt to urinate and i have no discharge i have been treated for the std's so maybe it is not bacterial and the doc gave me a pill for thrush.the syptoms did get better but it is still there. I have had also a problem with my stomach in the area just above the apendix it reacts to certain things and gives me quite a bit of pain it can last for weeks or hours but you can never be sure what will set it off.I hope you can make some sense of this as the doctors that I have been too and there have been many have no idea.
