It could be the stimulation of the nerves or it could be trapped gas pains. People with GERD and IBS tend to get these pains. I myself get sharp pains in my back and around my ribs. Sometimes in my chest. I do n ot get heartburn anymore with Nexium, suppliments and diet changes, b ut these pains are bothersome. I just started sometthing to help with gas pains so I will let everyone know if it works. I also just added Ginger to my routine.
