Hello N,
Most times this happens when I'm home with nothing going on. I'm a housewife with grown and married kids so no stress with that. The things I eat just before are different from pizza to beans and cornbread. I've tried to think of what would cause it so I could prevent it from happening because it is so unpleasant. My Doctor doesn't seem to know why it happens either.
Hi C, Try and think what happens before you get this, sound very much like a nervous reaction, the kind of thing some people get before an interview, stress can do this as well,
Please come back.
