Chest discomfort. Valuable suggestion!

On July 30,i had a severe chest pain and palpitation in the middle of the chest.i went to doctor in emergency he consulted that it is not related to heart ,it is  gastritis issue..!! Still chest heavyness,neck congestion, was continue to happen..the acidity issue gone fine within month ...!! last month end of aug , i again consulted doctor as the doctor knews my family history. so she told for chest xray.x ray report shows mild infection and she suggested for montaux test and chest CT scan. but CT scan report was normal.so she gave me medicine for infection and acidity . still the chest feeling is not good..now it started causing sudden pinch pain in middle chest,nausea,and hands pain..sometimes it feels like am breathing wrong.! Reports are attached along. Please give your valuable suggestion Thanks you in advance.
