recently I performed an certain activity and just as I finished, I started to loose my vision, and I felt some chest pain. I jumped up and ran down stairs and started freaking out and then I laid down on the couch and waited a few minutes, and I started to feel better. I felt like I was really close to passing out!
Also, for the past two weeks I have been getting bad head rush(when you are lying down, and then stand up real fast)
I am worried this might be a heart problem
