With the number of comments on this post, I doubt anyone will read this, much less the OP, but I feel compelled to say:

GO TO THE FUCKING DOCTOR!!!

If you're noticing something wrong or different with your body, go to the doctor to rule out something medical. Then continue your investigation. A doctor wouldn't try to diagnose you based on what you've written in your original post, so I wouldn't weight too heavily the opinions of a bunch of NON-DOCTORS with zero skin in the game.
