Actress Priyanka Chopra made headlines last week after suffering an injury on the set of her TV show Quantico. According to TMZ, Chopra was rushed to the ER after she slipped and fell during a stunt, hitting her head so hard that she suffered a concussion. She was discharged a few hours later.

Chopra made her first post-injury appearance at Wednesday night’s People’s Choice Awards, where she won Favorite Dramatic TV Show Actress. “I was a little nervous…. I didn’t know if I would make it, but I got so bored sitting on my couch for three days,” Chopra said on the red carpet, according to People. Chopra, 34, called the injury "scary," but added that her doctors say she should be OK in a few more days.

According to the Mayo Clinic, a concussion is a traumatic brain injury that changes the way your brain functions, and it's usually temporary. Concussions are fairly common, especially among people who play a contact sport, the clinic says.

Women’s health expert Jennifer Wider, M.D., tells SELF that the brain is surrounded by cerebrospinal fluid and is protected by your bony skull. “The fluid protects the brain, but if you suffer a hard hit—playground injury, bike accident, falls, fights, sports injury, etc., the brain can bang into the skull, resulting in a concussion,” she says.

There’s a range of concussion symptoms, but they can include headache, nausea, vomiting, dizziness, balance problems, cognition issues, difficulty remembering, difficulty concentrating, sensitivity to light, change in mood, slurred speech, extreme drowsiness, and loss of consciousness. “Some symptoms are mild, while others can be severe,” Wider says.

Emerging evidence suggests there may be subtle changes in the anatomy of the brain following a concussion, and there may be scenarios when people have structural changes to their brains after a concussion as well, Vernon Williams, M.D., director of the Kerlan-Jobe Center for Sports Neurology & Pain Medicine in Los Angeles and consulting team physician to the Los Angeles Rams, tells SELF.

Williams also says the recommended treatment for concussions is evolving. “Classically, the default was to let the brain rest,” he says. “It was felt that rest and avoidance of physical and cognitive exertion was the best thing to let the brain heal and recover.”

However, he says doctors now think the brain may actually do better when it’s stimulated about four or five days after a person suffers a concussion. The current recommendation now tends to be immediate rest, followed by some physical and mental exertion, he says, like going to the gym and doing a crossword puzzle. Doctors may also recommend painkillers for headaches and pain relief, Wider says. “We’re now much more aggressive in treating symptoms, like a headache or vision problems, whereas we used to take a ‘wait and see’ approach,” Williams says.

Most people will recover from a concussion in 10 to 14 days, Williams says, but Wider notes that recovery time can vary depending on the injury, a person’s age, and how well they take care of themselves after their injury. However, most concussions are thought to be fairly mild. “This injury to the brain is normally self-limited,” Williams says.

Concussions are still being studied, and Williams says doctors are learning more about them on a regular basis. “The take-home message is that it’s not an injury that we expect people to have long-term consequences from,” he says. However, if you suspect that you have a concussion, seek medical attention immediately
