Thank you for your advice. Still have swelling. I did mention it to my Doc …he checked and said it was nothing??? I am 30 yrs old with three beautiful children, have become convinced I have some form of cancer. I was recently in the hospital overnight with A-fib. Converted on my own with beta-blocker after @24 hours. This pain in my ribs swelling is just under my left brest it seems like my ribs stick out farther in that area also sweling of chest wall up to clavicle.There is also a clicking noise in left clavicle it seems to be coming from where it meets my sternum. I am constantly worrying and becoming a little obsessive about the whole thing. Once again I thank you for your advice any other advice would be most welcome.
