Hello, I Had Crushing Chest And Back Pain On Tuesday

Hello, I had crushing chest and back pain on Tuesday morning and on Wednesday it started again I went to the ER they took blood and an ekg all was clear they gave nitro if the pain comes back. I was to have a stress test today at the same hospital (ER) but they did not schedule it the cardo Dr did not have my er records and did another ekg again clear since they could not run a stress test he gave me Plavix and metoprolol. Should I take this medicine and also think I need to find better care.
