I'm lucky that the GPs in my usual practice are good. You know the GPs in your practice and what they're usually like so I'm not challenging your judgement of the GPs you know.
However, in general, I do have some sympathy with GPs over masking, and I say that as someone who, whilst not as dependent as you are on lipreading, am heavily reliant on it.
You say do a lateral flow test and that's logical but sadly they wouldn't know whether you had.
GPs are under so much pressure that not only are GP numbers still decreasing, more and more GPs are resigning from partnership to take salaried jobs, which in effect means they can limit their hours and get less aggro.
The BMA did some research last summer and found that over half the two thousand GPs who responded said they have mental health conditions such as anxiety, stress, burnout etc.
You may say well doctors are stressed anyway, hence the horribly high suicide rates in the profession even before the pandemic, but the aggro they have been getting during the pandemic, like the GP in Manchester who recently had his skull smashed by an angry patient, takes its toll.
Meanwhile, they see how people with covid-19 can suffer, and they can read what doctors with long covid say they're going throuh, and they can read what doctors with ME/CFS say about what they go through, and be frightened.
What I find difficult about all this is that I think that it would have been perfectly feasible for the government, instead of lining the pockets of their mates with scandalously high sums for basic PPE, a lot of it unusable, had kitted doctors out with really good stuff, including, by now, adequate supplies of masks with clear panels in the middle to facilitate lipreading.
Meanwhile, over time I've been asking various health professionals and receptionists etc. a particular question and the response is consistent. I ask whether there's a field on the screen that first comes up when they type in your name that contains information about your communication or access needs. Everyone I've asked has said no. It's expletive ridiculous.
So as I say, you know your GP, and what he did or didn't already know about you and what you'd normally, reasonably expect. I trust your judgement on that.
By contrast, I think a high proportion of GPs and other health professionals are on a hiding to nothing over this.
I'm still dreading my appointment next week in a secondary care clinic. I'm less fussed about whether they're ok to take their mask down than whether they're ok to repeat, gesture, write etc. But it's the same underlying problem.
Big hugs.
