Oh my goodness! That's awful! No wonder you are so distraught!!  I am so sorry this is happening to you. Glad that they have agreed to do it under epidural.

Did they say why you can't have an anesthetic? What has Covid got to do with it?xx

I've only just found this post, so my answer is way too late - but might be of interest to someone, somewhere. 

I have been in a similar position to the original questioner: I needed an urgent hysteroscopy during the early months of the pandemic. I assume she has had her procedure by now, and hope the results weren't too bad, but I can understand her frustration, because for some reason, hospital staff don't explain the situation.  In my case, a worried friend did: 

What has covid got to do with anything?  According to my friend (who is a consultant anaesthetist), having covid plus a general anaesthetic raises your chance of dying from complications of the GA from  roughly 1 / 100,000 to  something closer to 1 / 3.  (I also found this information on the internet at the time, but googled it just before replying here, and can't see it anywhere now.  Perhaps the 1 in 3 statistic has changed?  But a hugely increased risk remains, nevertheless.)  The increased risk continues for some time after recovering from covid, too - and my friend says that at his hospital they would still cancel an elective procedure for at least 8 weeks after the patient recovered from covid.  

I've had the same procedure a few times now.  Although "guidelines" have recently been changed and covid is everywhere - my hospital has stopped advising patients to isolate beforehand, and has stopped routinely testing patients for covid before they have a GA.  My friend said he recommends that I isolate anyway, and test myself immediately before admission.
