mini stroke

[Larrydog]

I had a mini stroke 30th june 2017, I am 70, extremely fit, ticked all the boxes for health, previously 2010 had ''heart event'' no one can tell me what it was, all that I have been told is I have an unusual heart rhythm. I think I had a mini stroke 3 yrs ago, which I never reported. I am due to have 7 days heart monitor. I am back at the gym. but get a pain behind left breast, I have also had pericarditis twice. anyone know what this pain is it is not, a huge pain, just comes and goes. I walk3 miles per day, and have 2 dogs they get separate walks. have to see consultant in October 2017.
