'How could my head do that to my body?'
Dungannon-born businessman John Kelly was driving to Dublin for work when he felt a tightness in his chest and pins and needles in his arm.
He called an ambulance and spent the next three days in the hospital for extensive tests, but these all came back clear.
“I was visited by a doctor who said the problem wasn’t with my heart," he said.
"When I asked what the problem was, he pointed to my head.”
John had experienced a severe panic attack.
