Chest & Breathing Problems

I am 26 years old ..I am having a pain on the right side of the chest just below the right side shoulder collar bone ..it's been there for almost 3 months now .The pain is increasing day by day .I am not sure which doctor to consult for this issue . I consulted cardiologist he said my heart is fine and no issues

Ive had this for 3 weeks now; I've gone to 2 doctors and an ER theyve done tests, everything's normal and fine. Got diagnosed witu costochondritis bcause of sternum pain. Still, my concern is my breathing. I feel like Ican only fill 3/4 of my lung wen I breathe deeply. Not deadly, but frustrating. Good blood oxygenation so Drs aint concerned. I am.
