Is there anything else it could be I am getting really scared now that something can be really wrong with me.?

Find a Dr. to trust. As president franklin d. Roosevelt once said, in 1933 about 80 years ago, ". . . Let me assert my firm belief that the only thing we have to fear is fear itself . . . ". Medicine is full of uncertainties, so one must find a doctor to trust. If that doctor says don't worry, then one must not be afraid. A good doctor will let his patient know when the time comes to worry, no sooner and no later.
