hi guys I need advice I have been getting left arm pain for 2 weeks or so but after i was given pulmicort in the emergency room the pulmicort is for asthma and its cortisone,

they gave me the med via the nebulizer machine.anyway when i got home I started getting episodesthis all happens suddenly not sure if its a hear pro
blem or a side effect of the cortisone since i took it 2 days ago

LOW BP

FAST HEARTBEAT

PRESSURE IN CHEST--NOT SURE IF ITS GAS OR HEART

FELT LIKE PASSING OUT

VERY DIZZY

NAUSEA

LEFT ARM PAIN/SHOULDER PAIN

SHORTNESS OF BREATH

I HAD A CATSCN OF THE HEART 2 DAYS AGO WITH IDOINE CONTRAST AND IT WAS NORMAL-I AM NOT SURE IF THIS TEST IS ACCURATE I AM SO SCARED I MIGHT HAVE A HEART CONDITION SINCE I HAVE 2 SMALL KIDS. BUT AFTER THE CORTISONE THE EPISODES HAVE WORSEN, THE PHARMACIST SAYS THE CORTISONE SHOULD BE OUT OF MY BODY IN 24 HRS BUT I DOUBT THATS TRUE SINCE MY CHEEKS ARE GETTING RED ALL THE SUDDEN ANY ADVICE
