Awhhhh, NowIsAll, of course you're scared.
Not knowing what's going on can be very frightening.
And being worried about what the doctor might say is understandable too. I think all of us have been through that and are facing it again.

However, the best way, IMHO, to face this is to get it over with... to hear what a qualified dr has to say. Maybe, just maybe, it will be news that you can easily handle.
So go ahead like Sue and Julie said and keep a diary, a log, about what's happening to you to show to a doctor. It will make an appointment so much easier and more complete.
Good luck .... keep talking to us, please. Here's a big hug from the group
