I had stomach pain too. It took a few weeks to develop. It occurred right where the pill sat after I took it in the morning, that is, the bottom of my stomach. The pain got steadily worse and worse. It felt like my stomach was turning from soft and supple to leathery. I had trouble sitting still or in one place for any duration because of this pain. After quitting the medication, it took 2 days before my stomach started to feel noticably better. Then about a week off the med I was positive it had been the lisinopril causing the stomach irritation. Problem has been gone and never came back. Thankfully, for me this symptom was not one of those semi-permanent or super long lasting ones that this med is notorious for.
