I am having trouble breathing for a month now. First i took my inhaler that i use occasionally for allergy (requires rarely) but then it didn't help. I started feeling like weight on my chest and wasn't breathing properly. Went to doctor he have me minolast medicines for allergy. Then i got fever and chills. Got tested for covid negative. Doctor gave me paracetamol and cefixime along with allergy medicine. I was fine in few days but again had breathing problem. Got chest xray done. Report is normal. However I'm curious about the circular structure on the right side of my chest. I attached the file. Hope its visible. Is it just a normal thing.
