I am currently 6 weeks PO and experience left shoulder pain almost every time I eat. Sometimes it is a minor nuisance, while sometimes it is agony that has me screaming in pain. I've noticed that the bad ones happen when I have meat. It normally lasts about 20 minutes and the pains feel like intervals of spasms and nerve pain. I am aware this could have something to do with gas, nerves, and the diaphragm. Can anyone elaborate on this issue? Also how long is too long? Is there treatment?
