MASSIVE chest pain near my heart.

I had this massive pain in my chest, precisely in a point above my heart. In the beginning it was unnoticeable but now ( after like 5 days ) it hurts so much that i cant laugh, sneeze, cough, clean my nose, without getting hurt. When i look at my chest in the mirror, i can see that there's a swelling where it hurts, and my mom was applying a cream she noticed that this swelling was not soft from the inside. It was very hard and the moment she touched it it hurt me so much. So now i kind of got used to this pain. I have done a blood test ( a doctor recommended one ) and i realised that mostly everything was good except for 'monocyte' ( the avergae was 5-10 and I had 16 ) I'm 17, very actif ( well i used to before this issue ), a bit asthmatic.
