I'm 35 and I've been having this weird pain between my lungs and rib cage on the right side. There's this indentation under my right rib where the bone kind of sticks out, and now the deepest part on the left is starting to hurt too. It gets really bad when I cough, sneeze, or jump on a trampoline. This all started after I had a really bad lung cold a while ago, and even though it's been almost 10 years, I still get mucus every day and the cold feels like it's never completely gone. What could be going on with these symptoms?
