Whenever I walk then I get choking sensation in my chest and throat.. it sometimes occur at rest also.. Yestedsy had left arm pain so got me worried n went to doctor for TMT. Now during test I did experience mild burning in chest and warm ness n discomfort in left arm which stayed after test also but my doctor told me test is negative n symptoms do not correlate with ecg.. I was also diagnosed with LPR by ent n cardio told me LPR can cause such sensations along with anxiety or muscular issues n again refer to ENT I just want to know is this correct path? Shall I walk n do activity freely widout worrying about pains
