Kena,

Stimulants of all kinds are pervading our society, and they can unleash a
disastrous effect on some people.   This will be a strange post, but try to
see if it applies to you.    Some friend or relative could be on a stimulant
and by a mind/body connection translates to harm to a vulnerable person and
you don't have to be in the same room with the person for the harm to be
there, you could be miles apart.    read my layman's theory on website
http://ascc..healingwell.com/info/gailfaq.htm           It is a strange
theory, but I am certain of it from observation and experience.   Manmade
problems.    could your mother be on an anti-depressant?  that is a common
med that causes problems to a second person.
Better you do not run too much or vigorously at this time until problem is
solved.
I could be wrong on the cause in your case, but  a physicians exam would be
helpful.
physicians do not know what I am saying, but in this illness, they are not
the final word.\
Other meds can cause the illness commonly known as Crohns, like Xanax,
Buspar, Depakote, Flexeril, natural herbs with natural stimulants, kava
kava, st johns wort, SAMe  etc. etc. etc.
Hope you find the cause and get well if the unknowing offender helps you.
I have a similar problem so I know how scary it is.
