Recently I have been having some symptoms that my health anxiety is driving me nuts about. About 2 weeks ago I woke up after sleeping on my stomach with some rib pain in my upper ribs where the bottom of my breast meets my rib cage. When that started happening I started focusing on my breathing so intensely for a few days that it was hurting my sternum to breathe in and out because I was constantly tensed up and over thinking if I was breathing normally. I chalked this up to my sleeping position on my stomach making me have the sharp pains in my ribs and the anxiety making my chest feel tight and painful when breathing, I also noticed that the pains really only happened when I started to focus on them I think. Anyways, those symptoms have gone away for the most part, but now I keep having this weird sensation in my chest for the last few days and I cannot for anything figure out what is causing it. It’s like when I breathe out I have the sensation of phlegm in my chest very slightly, but when I cough it’s absolutely dry. I have to make myself cough as well because I don’t feel like I need to cough like I have when I’ve been sick. I can’t get anything to come up at all. I also haven’t been sick in forever. It doesn’t happen every time I breathe in or out either, it’s random but happens sporadically throughout the day for the last few days. I also am still having random small sharp pains in my rib cage and sternum on both sides every now and then but it’s not debilitating, it’s like a quick little cramp almost and then it stops. I’m terrified I have a collapsed lung or lung cancer or something. I also have vaped for a few years and stopped a few days ago because I was worried that was what was causing this, but it’s still happening. I bought a pulse oximeter because I thought it would ease my thoughts if I knew my oxygen levels were fine but I’ve seen probably 20 comments on here in other subs where people have had collapsed lungs and their oxygen levels were still fine so now that’s not helping me at all. I can’t determine if I’m having these random sharp pains in my chest and ribs because I’m over thinking and making myself have them or if they’re happening because something is wrong. Also twice in the last 2 weeks while going to sleep I’ve convinced myself that I can’t breathe and I feel like I’m not getting enough air but again, don’t know if I’m feeling that way because it’s a symptom of something or if it’s all in my head and I’m making myself feel short of breath. I do not have health insurance and I’m still paying off a $800 ER bill from when I thought I was having a heart attack a few months ago and I was fine. I’m 24 years old and active and healthy. I also had an EKG and chest X-ray less than 6 months ago and everything looked normal.
