“Took about four or five months to figure out what it was.
“We went through CT scans, X-rays, cardioid measurement. We had ultrasound on my heart. We had measurement of the blood vessels on my neck. You name it, we did it, sinus, CT scan measurements, infection checks and everything.
“And we couldn’t find anything. There was literally nothing.

“And immediately from after changing the way I was breathing, the way I was feeling that day from breathing, it took it out. It literally just went away.

“Ever since then, I’ve been okay. So knock-on-wood.”
