I think it is nerve wracking OP but needs to be done. I have a condition that requires medical intervention so have had to go in. It's worrying but was fine.
A much higher staff presence IMO, at entrances where you are diverted to where to wait, made to use hand gel (so cannot sure whether they would accept you wearing gloves throughout a visit) and given a mask if for some reason you have not brought your own.
It was obviously much quieter than usual and waiting areas are very spread out. I would not expect this to mean there is less wait though. I have waited quite a while each time as they have to fully wipe down the room and equipment very stringently between every patient so that adds more time than you might think, especially if appointments also run over.
For me it was a bit unsettling but very bearable and a case of mind over matter. The first and 2nd time I went in I did upset myself in the days after (thisnwazdueing the peak) thinking "is that it have I got it then, in a few days I'll get symptoms and regret ever going in". Was fine on all occasions, other than the shock of my own anxiety having not been anxious prior.
All the staff seem very confident and upbeat which does give a sense of normality. If they are there day in day out and managing then I do think we as patients can manage the same. Rejecting media treatment and making yourself iller benefits nobody and may mean you end up in a ward as an inpatient.
Best wishes OP, for your health and the visit. It will be fine
