I've been having fatigue, left arm pain and foggy brain to the point where I have a hard time putting a sentence together. Can this be some sort of heart problem?

I've been having fatigue, left arm pain and foggy brain to the point where I have a hard time putting a sentence together. Can this be some sort of heart problem?

Yes, but...: If you're 24, it's very unlikely for this to be a heart attack or stroke. If you were 60, and this just started 10 minutes ago, i'd be very worried and would recommend the er immediately via ambulance (911).

How do u get a full evaluation of the brain, heart, blood? I'm getting very lightheaded & has had mri&ct 6mths ago normal. & had a full blood work up!

Hmmm...: Well, I doubt we'll be able to do this in 400 characters, but the lightheadedness is often broken down into several categories. If it's fainting or near-fainting spells, that's called syncope or near-syncope and we usually check with a cardiologist about that. If it's like the sensation you get when you stand up too fast, it may be low blood pressure, especially if you're on meds. ...Read more

Random episodes of dizziness & lightheadedness/fainting with brain fog. BP & heart rate normal. CT scan & all blood work normal. What can it be?

Dizzyness: What a waste of money and resources doing all those tests on a 19 year old with history of anxiety, especially if liver disease is under control. If its positional, you have BPPV O/W vestibulitis, but there is no fainting. You have "panic attacks". I know most doctors practice defensive medicine especially in ER. ...Read more

During a concert I wasVERY excited. My heart was beating VERY fast and erratically at times for at least 15 minutes. Can I have damaged heart and brain?

During a concert I wasVERY excited. My heart was beating VERY fast and erratically at times for at least 15 minutes. Can I have damaged heart and brain?

Not usually: It is possible to have an irregular heartbeat due to excitement but this is "normal" under those circumstances. There is no permanent damage.

Such elevation of heart rate is generally considered to be part and parcel of a healthy exercise program. ...Read more
