Update. Went to surgeon and explained all symptoms and he agreed it sounded like classic hernia. He did an ultrasound to be sure, but found no hernia and of course the bulge was not there while he was doing the exam. He came to the conclusion that I strained a muscle and the symptoms could be the same. I suppose the bulge I have been getting is the muscle on the lower right side of my abdomen near my groin. I was relieved because I do not want to have surgery, but he wants me to watch it and go back in in 3 weeks. I think I'll just go to a gastro guy and do the colonoscopy (which I am due) and see if there is anything there.
