I have small internal hard bump just above stomach and center of the ribs.. it does not hurt and it's there for 2 years or so..?

Observe: It definitely doesn't sound serious if it has persisted unchanged for two years and has not grown or gotten painful. It may be a cyst or a lipoma, a benign fatty tumor, commonly found on people. If really wondering, go to a doctor and have him look.

Lump: It could be simple things like lipoma ( collection of fat cells) , cyst sebaceous cyst or more dangerous lumps . Please get checked by your doctor.
