Hillary Clinton broke out into a coughing fit while speaking in Harlem.
On Tuesday, the presidential hopeful was discussing race relations when she started coughing and couldn't stop for two minutes. Drinking water and having a lozenge didn't work.
The crowd chanted "Hillary! Hillary!" to show their support but eventually she was able to speak again.
Her coughing bouts have occurred before; recently she was speaking in Iowa when she had a fit and also last year during a congressional hearing on the incident in Benghazi.
Does the presidential candidate have a medical issue?
INSIDE EDITION went to ear, nose and throat specialist Dr. Jonathan Aviv.
"It's not just cough," the doctor said. "There's some hoarseness, there some throat clearing, in fact there's frequent throat clearing. When you have these trio of symptoms, you have to think of what I call throat burn reflux, which is acid reflux affecting the throat."
Dr. Aviv says the former Secretary of State might have made a mistake by reaching for those lozenges.
If you're caught in an attack of acid reflux and can't stop coughing, the doctor tells us a lozenge is not the best way to go. There's actually a breathing technique that he says will shut off the cough like a light switch.
He says to "close your lips and sniff and instead of pushing the air out, tighten your core and as slowly as possible" make a small release in your lips and exhale.
