Trop test or tmt? Me what should i do?

I need some urgent suggestion So since the past four days I have been dealing with some major chest pains which resemble that of heart attack.. a deep crushing discomfort Radiating to my left arm n right arm I am unable to like get out of my bed n do anything without this discomfort. I am also not able to sleep Now I have had 3 ecg done from Monday to Thursday N none has shown any changes. I decided to get tropinine done today for confirmation but then it costs 1200 while stress TMT costs 2000.. So I want to know what it be better like if I directly go for TMT? I had tmt in September which was negative Now the symptoms have changed I want to see if on exertion there are any changes today Please suggest me what should I do??
