Bad Al for not going straight to the hospital Glad everything is OK mate , was your heart rate normal ie between 60-120bpm & regular . Al was your BP ok .Maybe you should get yourself a regular GP mate
You did the right thing checking in with NHS. I've had friends of friends being hospitalized for observation on cause of stress related heart ailments, and they were around 30.
As long as you never sell your toys, smoke, drink or be close to toxic chemicals and pretty women again you should be Ok.. All the best Al!!
Sounds scary mate. I know what you mean when you say you don't want to look "silly" and make a fuss but there is no doubt you did the right thing. Hope all goes well and take it easy.
