Pro Gamer Karma Admits 'PTSD' After Lightning Strike, 'Loud Noises Scared Me'

Karma -- the pro gamer who was struck by lightning while streaming on Twitch -- says she's no longer in physical pain ... but admits she's suffering a little "PTSD" after the crazy incident.

27-year-old Jaime Bickford was INSIDE her Boston-area home Sunday night commenting on a game of "Rocket League" when lightning struck ... and somehow, she got hit.

You can watch the live stream and HEAR the moment of impact -- it's really scary stuff.

Bickford tells TMZ Sports she's still not 100% sure how she got hit -- saying, "It all happened really fast."

"I was just commenting over this game and then a huge flash came out of my controller, like really bright," Bickford says.

"I just remember my hands burning and my body just automatically dropped the controller."

Bickford says her hands were sore for the next 2 days. But there was also mental trauma.

"I definitely had PTSD about it the day after -- just loud noises scared me. There was still thunderstorms the next day so I didn't want to touch the game just 'cause it freaked me out."

Don't get it twisted ... Bickford says she's definitely NOT walking away from gaming -- telling TMZ Sports she's worked too damn hard to quit.

As for the controller she had been using -- that's toast.
