I have been having shoulder, chest and neck pain on my RIGHT side that is driving me crazy, and it seems to have started when all of my silent reflux symptoms started. I keep thinking that something else is going on like an auto-immune problem or something. Are there special blood tests for those kinds of conditions?? I'm on protonix twice a day and singulair, which I am going to stop for a few days just to see if it's causing these pains. :confused:
