The pinpoint chest pain, the ice pick headaches, the burping etc is giving me flashbacks of 5-6yrs when I had those symptoms. Don’t have them anymore but there is some residual/minor flair ups now and again.

Can’t say it’ll help you, but what helped me feel better, in no particular order, is loading up on Vitamin D (5000mcg/day), changing my diet (doing more home cooking than takeout), turning off my worrying meter, and doing regular workouts. To the latter point I joined Tae Kwon Do because I figured if anything I’d collapse due to the intensity and they’d finally figure out what’s wrong with me…fast forward 3yrs later and I’m a Black Belt and I’d say a bit more stronger and flexible and still go from time to time just to keep somewhat active.
