do any of you shake a lot when something is feeling off? even if its relatively minor?

when my stomach is feeling off(not sick), or my bowels are off, or etc. etc...
especially when im in bed at night.. i'll just start shaking horribly! like whole body shakes. an overall tightening.
my mom used to get it too.. she went through a year of what she called a "bowel flareup"..and said it always went away after she went to the bathroom...

they'll go away eventually. but sometimes i can shake in bed for 15 minutes!
is this part of some kind of panic? or is this stemming from something going on inside my body?

anyone anyone?
