About a month ago I had dinner grilled meat and broccoli, at this time my mouth was sore,hours after eating I started having pain in my back ,under my right shoulder blade, dull stabbing pain. I thought may be it was gas I was going to take something,before I could, I started throwing up the food ,I assumed I had not chewed my food well. My back was sore until the next day. Since that incident I seem to have problems with gas,some constipation and back pain in the same area sometimes, also belching, but I have not had to throw up again. I don t have any pain in my chest or stomach. I am 53 and have never had any digestive issue until the incident mentioned above
