Then it kind of passed away and had a pain
and pressure feeling on the left side
of my throat.(Not exactly throat, it was right above my clavicle bone, inside a trachea or esophagus, I don't know). I felt more pressure when, for example, I was in bed and turned on the left side. I went to allergologist, did blood tests, chest-X ray, spirometry and consulted a cardiologist, all was normal. But after gastroscopy, i was diagnosed as reflux-esophagitus.
