Pulsating left side of stomach

I am a 30 yr old male. I have been having a pulsating feeling in my stomach towards the left side for four days now.  It comes and goes at random times throughout the day.  No pain, just spams for about 30 secs at a time. 1 year and half ago I had my appendix removed due to enlargement.  It kind of feels like the same sensation, before the pain.  My sister has colitis, so I don't know if it can be that.  Every search I run says it's AAA which has me panicing.  Any help would be appreciated.

Hi,
The pulsating feeling could be from the underlying big artery called aorta. If the heart rate is rapid or if the flow is hyperdynamic, you may feel this and it is normal.
