I have been autistic all of my life, but I've never experienced any symptoms of anxiety (mentally or physically) before.

over the past 8 months or so I've been having really bad chest pains, which led to an A&amp;E trip. I found out I have gastritis (which I've recovered from now) and costochondritis (inflammation of the cartilage between your ribs and sternum) which is still an ongoing problem.

these health problems have been pretty exhausting to deal with, but for the most part I've been having a pretty positive outlook and haven't had any issues mentally. the costo is still a problem but slowly improving.

however, in recent weeks I've noticed some strange physical symptoms that I believe are related to anxiety:

•a pain/sensation on the front of my neck, around my Adam's apple. it feels like it's itchy and makes me worry that I can't breathe properly. usually when this occurs I get hyperfixated on whether I can breathe properly

•a tightness in the chest that's different from my costo pain. it makes me worry I'm going to have a heart attack even though I know deep down I'm not

I've been checked by professionals and all my vital signs are clear - no health issues aside from the Costo.

the strange thing is I don't feel anxious in my head, there's nothing I can think of that has me particularly worried.

I'm 25M, regular height/build, balanced diet, haven't used any alcohol/weed/caffeine for 6 months now for reference.

has anyone else experienced similar before?
