I have recently developed this symptom is well. Roughly 15 minutes after I eat I developed a severe pain in my left shoulder that creeps up to my neck. It doesn’t seem to happen when I eat in the morning or at lunch almost exclusively in the evening. It is also not exacerbated by any movement although a deep breath can make the pain more intense. We eat fairly healthy at our house but I am prone to eating too much. I’m 38 years old and I exercise 4 to 6 times per week. I’m trying to get back to see my G.I. doc soon but I would love to have someone of a hunch going in
