Pippy, in just three posts you've descibed a handful of strange symptoms.That given, no one can help with sommething like this without seeing it. What you're describing sounds like a possible cyst or lymphoma, but there is no telling without having a look at it and potentially taking a biopsy.
So, see a gynecologist if you are really experiencing all these odd things. Don't wait.
