I have been experincing a sensation that I have to force myself to breath and an exact mild discomfort pain in middle of the chest like near the esophoogas? Could it be anxiety,gerd, reflux or something else?
Sorry to hear that, I hate that feeling in the chest especially not knowing.
Anxiety is indeed one of the most common occurences these days, many people contribute their chest pains to a heart attack and they go to the hospital, they then find out it was an anxiety attack. I took a friend once and that’s when I started to learn more. The problem is they send you on your way and that doesn’t help people manage or control it.
Have a look here, this program has been getting good results, best of luck.
