Welcome to heathcare Magic!
The pain in the chest at that site can be due to muscle spasms, Pleurisy/pneumonia/pericarditis-myocarditis
in which case it is more when you breath in and when you cough
and in angina/myocardial infarction
when it is constricting nature and not related to breathing or movements.
In any case you need a Chest Xray and an ECG and review to your physician.
Wish you a great health!
