You obviously think it might be something nasty to post on this
group.....please get it investigated, even if it means paying to go
private...Which I did.. Your GP will reccommend a local clinic and they will
arrange an apptmnt.... Will put your mind at rest,   peace of mind is
everything.....let us know how you get on... chances are it's nothing
'orrible.... Good luck
