I have had those days... many of those days... it is almost scary to read posts and think 'this person is describing ME'.
How can it be that no one medically can understand this when we all present such similar symptoms?
Best of luck to you. On the bad days, just remember the good ones. They will come. I have had a such a cycle of good/bad days. And while I HATE the bad, they make me appreciate the good.
