I got infected with cavity in january 2022. After recovery, since february 2022 I started having shortness of breath and chest pain problem. I consulted several doctors but none of them could help me. Few doctors said ,i don't have any problem as they couldn't find anything. I am suffering in silence. I also started having anxiety, depression and sleep issues. Sometimes shortness of breath becomes severe and I feel helpless. Shortness of breath is present most of the time, during sitting, lying down, walking please help me.
