I'm so pleased that your sister has that doctor's appointment, because any severe headache that doesn't go away can be very worrying.

As you have a computer I'm sure you've Googled just about everything that might be wrong. I know it's hard not to do this, but you have to believe that it's something simple, and try to leave the diagnosis to the doctors.

Just remember that the MRI showed nothing. If she had cancer or any other type of tumor, the MRI would have shown that.... so that's a plus!

I can certainly understand your concern though, and your sister is lucky to have a brother who cares as much as you do. I wish I had the same.

You did ask in your prior post if the doctor would phone once they'd read the report. From my experience they only ever ring if there's something life threatening, or at least something really bad that needs urgent attention, so if you don't hear anything at all... I'd take that as another plus.

Please let us know how your sister gets on, but in the meantime I'll be thinking of her, and hoping that all will be well.
