<bot>: Hello Nicole! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that it is necessary to perform a differential diagnosis for your recent complaints: Is it a cardiac ischemia (though it doesn't seem too much to be a cardiac disorders)? An acute pulmonary disorder? An abnormal neurological condition? Or something else?!! I recommend you to ask medical assistance to the nearest ER service to rule out/in serious health conditions. A careful physical examination, coupled with a resting ECG, some lab tests (complete blood count, PCR, including cardiac enzymes), a chest X-ray film, eventually a cardiac ultrasound, a cervical&thoracal thoracic X-ray film, etc. are necessary to identify etiological reason of your complaints. Hope the have been helpful! Greetings!
