Vibrating, shaking feeling..?!

Best Answer - Chosen by Voters

Could be just bowel related. My aunt who has diabetes complains once in awhile of
this strange, shaky feeling. On the serious side is abdominal aneursym......which can
cause strange sensations in the area between the belly button and chest. Often those
with this type aneursym describe it as pulsating, vibrating. Sometimes a Dr. will just
keep an eye on it. Other times surgery is needed. It usually depends on size.
Because it can rupture and be an emergancy I would mention it to my Dr. Odds are
it isn't the problem but we never know. I'm certainly no doctor.

i would go see a doctor if thats how you're feeling
