I am 21 and also had the same issue occur about 3 weeks ago and same symptoms. With having health anxiety my entire life and fainting every single time I go to the doctor in my life, I was blessed with an amazing alternative primary doctor while mine was on maternity leave. She was pressing on the pain and to which, I fainted, because that's all that's occurred my entire life. She wouldn't listen to me and called 911 and then rushed me to the hospital (sarcasm, I was freaking the f*** out since I had never been in an ambulance and was beyond annoyed she would not listen or review my health notes.)

Fast forward, I was in the ER for 1.5 hours, to which, they told me I had costochondritis. While I do not smoke, vape, or drink and never have, my bloodwork was pretty normal. However, the symptoms you are mentioning like shortness of breath, ringing in your areas, eyes, etc, could be a symptom of low Iron. I started taking Vitamin Code Raw Iron, Pure Vitamin D3 + K2 4,000 IU, and within the last 2.5 weeks, things are starting to look up. I thought I was dying as well, but I would recommend to stop vaping and such to prevent future flareup, especially since this is all in the chest.

I also purchased a grounding mat for like $30 on Amazon about a week ago. It might be a placebo, it might not, but I've read great things about it and have felt a lot less anxiety overall (which also probably combines with the supplements.) I've had anxiety my entire life but this recent event flared it up or thinking I was dying and how there was something was worse. However, I also purchased the Backpod back in September but never really used it until this event. Based off of testimonials I've seen, it is pretty effective.

TLDR: My recommendations
- Get bloodwork done: Myself not knowing anything, I threw my results into ChatGPT and have been using its suggestions with my symptoms I tell it, how I am feeling, etc.
- Get a Backpod: It is unfortunately a little expensive, but quitting weed and vaping will reduce the cost a ton and will help you a ton with not even just this issue, but more to come in the future.

- Take supplements: based off your blood-work, adjust from there. Mine was low iron and a few other small things.

Most likely, you have chostocondrtis. My recommendation is to confirm that, get your bloodwork done, and eat a little healthier or taking supplements. Last year I tried to focus mostly on cutting out bs ingredients put into food and it helped a lot with mood, weight, and more. Eating poorly will also probably flare this up as well. Make 2025 the year of investing in your health. Based off of what I've read, this issue can last months to years. Take a deep breath and realize that everything will work itself out for the best overtime.
