I'm glad that someone brought this up because I sometimes get these "heart attack" symptoms too - I just turned 30 so I shouldn't be having any problems with my heart. When I have my "episodes" (which have become MUCH less frequent since being diagnosed with Celiac), it hurts so bad that I actually think, "well, this may be how I die..." In fact, it landed me in the ER twice in one day because I couldn't take the pain - the doctors did a ECG which turned out completely normal, so an injection of Pepcid and Ativan was the second choice and knocked me right out. The pain came back 4 hours later. The pain builds up in my chest and comes in waves, but is consistently uncomfortable. Moving somewhat makes the pain subside but I end up engaging in this rocking motion that really freaks my husband out! I have definitely had symptoms of GERD also (burning in the chest and up the esophagus) and that also has subsided since eating gluten free. Do you guys think that the chest pain could be related too? I have varying glutening symptoms so sometimes its hard for me to pinpoint when I've actually been cross contaminated. While I'm sad for everyone else who's had to experience this, its a bit comforting to know that I'm not the only one who goes through this.
