Hi everyone. I have suffered from health anxiety for some years now. It comes in waves. Most of the time I try not to let it take over. However, I've had different attacks that took me 3-4 months to get over. Now I am again experiencing a heavy HA attack. It all started with some mechanical thoracic back pain, mostly in 1 spot in my vertebrae. Did an x-ray showed up as I have a slight scoliosis and also some reduction between the lumbar vertebrae spaces. Anyways, long story short, I had the x rays been given to me and decided to just take a look on them. After looking on those AP and Lateral view for some minutes, I spotted a white spot in my lung and immediately freaked out! I was thinking what if the doctor focused his attention on the vertebraes and didn't notice this shadow in the lung?? I was checking like crazy x rays on the internet and what I was seeing matched with my x rays. I started crying everyday thinking that smth has been missed and i might have the C thing. After 1 week of horrible stress and anxiety, I decided to go to a neurosurgeon about my back pain and also took the x-rays to show those to him. For my back pain he siggested physio and kinesiotherapy. He saw the x rays but didn't spot anything. And then I specifically pointed out on what I was looking at and asked him what was that spot. He took a 2 second look and said: It's a rib! 
Okay, relieved I left. And then I started looking again the x rays and in my eyes it doesn't look like a rib! Now ofc I think I should believe 2 expert opinions rather than me diagnosing myself over Google, but I also have the what ifs that are killing me... 🙄🙄
Sorry for taking your time, but I really needed to vent somewhere. Take care everyone!
