Today, during work i had a fluttery feeling in my chest, around my heart or lung, i have high blood Pressure, confirmed, and undiagnosed angina from multiple sources. I work as a groundskeeper( strenuous labor) And have had blood pressure issues in my neck and tightness in my chest from working to hard before. This is first time ive felt a sensation in that area other than the tightness that comes with angina. I recently (last 3 weeks) have quit smoking and gone to an electric cigarette, i am hoping that it is just a lung issue and possibly caused by the transition from smoke to vapor, but i am not sure and would like a professional opinion. For the record, the feeling i had didnt hurt, if anything it actually seemed to tickle
