Yo same kind of thing here. Pretty frequent surface level chest pain (chest wall), heart burn, spasms in chest and stomach, and belching and they're all "oh it's GERD and probably costochondritis" and then haven't done a single thing about it and it's driving me craaaaaaazy.
Mines still a problem now since I have a hiatal hernia but mostly changing my diet helped. I cut back certain things I knew aggravated it like caffiene then took out other foods to see what would happen. That's also when I stopped having bullshit old person joints. My knees and wrists hurt so much then and now if they bug me it's because I did something. I mean my knee would feel like it would give out at times and pushing myself up with my hand shot pain straight up my arm. All gone :) so it's worth trying different things and seeing what might work for you.
Do we have all the same problems. I'm pretty sure we have all the same problems.
