Hi there. This could be a heart attack and you need to see a cardiologist immediately for emergent intervention. Myocardial infarction pain is characteristically crushing retrosternal chest pain which may move to arms, shoulder, neck, teeth, jaw, belly area or back. This can be squeezing, lasting for 20 minutes. Rest and nitroglycerin may help relieve the pain to some extent. Other symptoms are anxiety, cough, dizziness, palpitations, shortness of breath etc. your doctor would like to check the cardiac enzymes like troponin and CPK, CPK MB. Continuous oxygen and morphine, anti thrombolytic therapy, anti arrhythmic, etc are required. You need to get an MRI cervical spine to check for any prolapsed disc or degeneration. Hope this helps. Take care.
Oh, dear. This signals a stroke or heart attack. Whomever is having these symptoms MUST go straight to the ER, and if they cannot transport themselves, call 9-1-1. That numbness on one side and nausea is a sure-fire sign of stroke, and it must be treated within a certain period of time to prevent damage from becoming permanent or disabling.
