Hi! I thought it was just me but now I know. I had burning and discomfort in my chest for months..it was reflux and it made me so sick on my stomach also. It’s scary because I thought it was my lungs too but I’m very grateful it was not. If I eat 3 hours before bed I’m ok if not I have to sit up or it will cause discomfort. And about the thumb does it have anything to do with our lungs? I have been having some horrible pains in my thumbs and it feels like I can’t use them at times. I thought it was RA. All the strange things in life. 🙂 hugs to all. Stay safe Rita.
