question: I just notice a big lump on the left side of my abdomen.  I had not notice it before.  It does not hurt when I touch or press on it.  It just feels a little hard but thats about it.  Any ideas?  P.S.  Ive been lifting weights lately but I dont recall hurting myself while doing it.  Im 54 years old white male.  Had a double bypass at age 43.  High blood pressure and slightly high cholesterol managed with medication.
