Guys, does anyone else experienced this..?
I live alone in Africa, away from my family for the job.

Have had tough times with stomach pain which only appears here, persistently, just below my sternum. It goes away only when I get plane ticket and travel home.
Now I have heart palpitations on top of this.
Done few ECGs, 24hr heart monitoring, blood test for thyroid and troponine.
Doctor says it is stress, advises to do some sport, but I can't bear it anymore. All comes in in the evening time when I am about going to bed..
