So i will keep this straight i have had tons of ecgs, echos and tmts last year.I don't really have problems except possible pots due to my symptoms like my HR just jumping to 120bpm when i walk, but that's not the problem the problem is the strong sharp chest pains i am getting today.They are happening every now and then,they happen at one small spot hurt for 2-3 seconds and goes away same with sometimes dull pains too they happen for 2-4 secs and go away while sometimes the small spot pain lasts for 30 secs to a minute which i found out is called as texidor's twinges.So the sharp pains last for few seconds happen at one spot or sometimes from one spot to feelings like multiple wires in my chest wall hurting for a seconds and it goes away even with dull pains that stop in seconds too.I have been coughing for last few days by the way.So doc is this related to my heart?sharp pains are strong sometimes and yes streching can sometimes make it feel more painful before it stops.
