I've had 2 surgeries in 4 years, and had problems afterwards because of the anesthesia. The biggest problem has been with balance, which I never had before the surgery. I've also had memory and cognitive function problems as well. I've read articles on the internet about the latter, but have yet to see anything about the balance and walking problems. Anybody out there have those problems or know of anybody who has them? Would like some input if you do know anything about the subject. Thank you!
