Hi doctor, on Wednesday and Thursday I had left chest pain on and off for the whole day but it was not so severe, i ignored it as i recently had checked my BP and it was normal, yesterday i had kind of heavy feeling in the chest, little lightheaded, fast heartbeat. I went to doctor yesterday night, he checked BP, heart rate and ECG, everything was normal, but still gave me half clonazepam tablet, i took it and slept nicely but today also i am feeling the same feeling in my chest... i am very much worried, what it might be
