Over the past year strange things have been happening. I woke up one morning walked a bit then got really dizzy I leaned against the wall and it felt like my entire body was shaking but I couldn t control it. I fell to the floor but after a few minutes everything went back to normal. A few days passed and out of no where my heart would get a sudden pain that lasted about 5 seconds but the pain was strong enough to make me cry. This continues randomly at any time or place. I had several dizzy spells and times where it felt like I couldn t talk because opening my mouth hurt. Taking in a deep breath would hurt my throat and chest that too happens randomly. I didn t talk to my doctor about it because I don t really know what the problem is. Should I be worried or is it just random stuff happening to me?
