Obviously I understand that online diagnosis is not realistic, but I wanted to describe what I am feeling and get some opinions.
I am a 29 year old male. 6'0", 215lbs. My diet is not all that great, but I do eat some veggies and take vitamins. I checked my blood pressure and it is normal.
I am also a little asthmatic, and I have recurring battles with stomach acid.
However, this new discomfort is unusual to me.
This has been happening just the last two days. When I run up the stairs at my work, I can feel a discomfort in my chest. The best way to describe it would be that there is a dull pain in the center of my chest, and in my throat it is cold and feels like something small is in my throat, a lump in my throat. I can breathe normally, there is no loss of air or lung capacity, just a lump in the throat.
The pain in the chest is dull, and it is noticable that my heart is beating.
All of this lasts only about 10 or 15 seconds, and then the pain and discomfort goes away completely. (until I run up the stairs again, or get my pulse going).
On the first day, I exercised on my Eliptical Machine. The first 45 seconds of the exercise, I could feel the dull ache, but for the rest of the 4 minutes that I was on the machine I really didnt feel anything.
I would hope that nothing is wrong with my heart. Any ideas what this is?
