I am a 44 year old male and I have naion in my right eye that happened to me after a really bad covid infection in July of 2021 that had me hospitalized for 5 days. I recently had 2 separate surgeries on both my feet both times requiring me to be on anesthesia my anesthesiologist informed me of the risks of another nation even happening but he said they would take measures to minimize and blood pressure problems. I went through both surgeries 3 months apart without any problems. But there is always a risk. I hope this helps.?
