It's uncommon and the risk factors stated probably don't apply to you but, as with so many conditions, it's not impossible that people who don't fall within those risk factors could be affected.
If it's troubling you greatly, then a trip to your GP would be the best idea and at least you'll get a proper diagnosis as opposed to possibilites!! :-)
