Hi, I'm 16 and I have this really uncomfortable feeling in my thyroid area, it's like a choking sensation whenever I breathe in or it kind of feels like someone has their thumb under my Adams apple and is putting pressure there. This has been going on for three months and there are some days where I barely notice the sensation or I don't even notice it at all, but it has become a concern for me and I've been worried so much about it, I always think that I might suffocate and die. I've had an ultrasound done on my neck last month and it came out normal but I still feel it, I try to not worry a lot and that helps sometimes but I don't know why my throat feels like this, it may be related to flexing my throat muscles before or it could just be anxiety and I'm thinking about it way too much, but who knows. I've also had shortness of breath and difficulty breathing to go along with the sensation, though I don't have them anymore, no trouble swallowing though, and I have no asthma either.
