Will Flying with a concussion possibly cause any health concerns?
Hi, I was a flight attendant for 9 years and I never heard of concussions being a risk when flying as a passenger. If your doctor cleared you to fly, that is a good indicator that things should be fine. Nonetheless, upon boarding the flight, I would let the flight attendants know about your concern. This way, if anything was to happen to you in-flight, they will know to give this information to any medical staff who may help you. It will also allow you to have some peace of mind, as anxiety is likely a worse state than being concussed when flying.
