Yes Please. Last Friday I Was Having Sex And I

Yes please. Last Friday I was having sex and I had an unusually strong orgasm. When finishing I experience a deep squeeze in my heart followed by pain. Later I felt a sudden fatigue and yesterday I experienced flu like symptoms with pain in between my shoulder blades and headache. I had Tylenol yesterday and today but the pain in the chest continues. Not as strong ask Dean moment of the orgasm, but I still feel pressure. I wonder if it was a heart attack. Or water was it?
