Please look into Postural Orthostatic Tachycardia Syndrome (POTS). It is a very unheard of nervous system disorder that prevents the body from being able to properly adjust to the pull of gravity. Therefore, symptoms arise, such as: rapid heart rate upon standing, low or high blood pressure, dizziness, fainting, fatigue, sweating, anxiety-like symptoms, headaches, shortness of breath, inability to exercise, digestion problems, etc. The symptoms are endless and vary person to person day to day. Very few doctors are familiar with this illness and often misdiagnose patients.
Please feel free to contact me if you have any questions.
It sounds as though you know the warning signs of heart disease, and that is a good thing.
Generally speaking, anyone who experiences these symptoms should be seen by a doctor, preferably as they are occurring.
I don't know how severe your pain is, how long it lasts, what relieves it, but common sense would dictate that the next time you feel this way, you should go straight away to the ER to be evaluated.
It may turn out to be something minor, but you have described symptoms that need to be checked out while they are present.
I'm fairly active but I work as a nursing assistant so i'm constantly moving pulling, lifting, walking and this is even beginning to be a struggle. and i drink plenty of water all day so i will take your suggestion and get a second opinion.
To be honest I would go back or seek a second opinion. The nuclear stress test should have given some kind of indication whether or not you had blocked arteries but there may be other causes for your symptoms that maybe aren't related to the arteries. So how active are you? Is this with minor exertion or after really working out? Do you stay well hydrated? Were these symptoms a sudden onset and do them come and go? I might suggest if you do strenuously work out to take it easy for a while. It could be your heart is a bit worn out maybe even from a virus and it needs some time to recuperate and then will be fine but I would definitely go back and let them know how much you are struggling and/or go seek a second opinion. I do hope you feel better soon and keep us posted on how you are doing.
