One day while i was eating peanut butter crunchy it got stuck in my food pipe and then i was having some pain on my left side chest..it's been three months since it happened..but i still feel some kind of pain on my chest region..and sometimes my heartbeat elevates for no reason..even if I'm lying down on the bed... I just want to know if there's any connection between both these incidents i.e the peanut butter and my heart rate. I wanna know if theres something wrong with my heart or it's just all in my mind. P.S. i have done ECG and Echo tests and the results were normal. Thank you doctor for reading this. Waiting for your reply.
