When I had my gallbladder removed a year ago I had gas pains in my trap muscles/ neck well I'm having pains now that feel similar to that but goes from my shoulder to my neck and up a little to about my hair line on the back of my head. it intensifies when I breath or swallow especially if I breath extremely deep. It started two days ago and felt like my collar bone was hurting and when I woke up this morning it was worse. Could that be gas pains because it's starting to worry me.
