KENOSHA, Wis., (SPECTRUM NEWS)— Gaige Grosskreutz is ready to share his story for the first time since being shot in Kenosha. 

Police and prosecutors say that 17-year-old Kyle Rittenhouse shot three people during Kenosha protests. Two of them were killed, and the third was injured.

The sole survivor, Grosskreutz, is just 22-years-old and says that night is constantly playing in his head.

Grosskreutz isn't from Kenosha. He's a Milwaukee-man, who made the trip south not only to protest the shooting of Jacob Blake, but to provide first aid to those in need of help. He's a trained paramedic. 

Despite those intentions, he was the one who would ultimately need treatment. 

He was able to use his own medic bag to treat the gunshot wound. CJ Halliburton, who was streaming the incident, stopped what he was doing to lend a hand. He helped Grosskreutz apply a tourniquet to his arm before being driven to the hospital by police.

"Now missing 90 percent of my bicep. This has not been easy emotionally and physically. I'm in constant pain, like excruciating pain, pain that just doesn't go away, both in my arm and in my heart, in all honesty. I was lucky enough to walk away with my life. There are two people who didn't," he tells CNN in an interview. 

He is still being treated in the hospital. He is at the same hospital as Blake.

Rittenhouse, who is currently behind bars in Illinois, is charged with a slew of felonies. His attorney is arguing that Rittenhouse was acting in self-defense. 

Grosskreutz says he and his family are getting death threats from Rittenhouse's supporters. 

"None of it is true, of what people have been saying as far as their assumptions toward me, at least," he says. "I'm not an Antifa terrorist organizer. I am a 22-year-old male. I go to school. And yeah, I exercise my First Amendment right to peacefully protest."
