Hi. I don't know if it's anxiety related or GERD but I have been experiencing burning sensation on my upper left chest and pain in left arm after physical activities like walking or when stressed since 1 week..I did several ecg, echo and blood tests but everything is perfectly fine.. I was put on 10 mg inderal for 20 days and started seeing a psychologist Which made me feel much better and I stopped inderal... But each time I get the chest and arm pain, I panic and start having all kinds of thoughts.. Help please
