Hi, I am suffering from chest pain for last three years, i did many test, every year ECH,ECHO,TMT every year. And report came normal this time few days back i did CT Scan of the chest and its also came normal, i dint understand what is the problem, pain triggered more when i lift some items and do some physical work. Plz suggest what is this all about should i go for cardiac MRI or what test help to diagnose the pain as far as i remember this whole story started when once i lift dumbels back than in 2017. If its muscle pain does it last that much time? Thanks
