Since lockdown i have anxiety issue. Sometimes feeling like I might get heart attack and die. Due to which I often feel anxious and when anxious I get chest pain at left side starts from middle like tingling sensation. I also get some left hand pain and it will subcide on its own. Daily morning I get loose stools only once sometimes. Apart form that I was healthy before that. I feel like some vibration like feeling upper back side and upper chest area(left). Im really scared to know if it is not something serious. Please help me to understand this.
