Having just gone through this, I can say. There are few diagnosed problems , on the list offered by public health England, that doctors must adhere to when handing out exemptions. If you don't suffer from any of those, you haven't a hope of getting an exemption. " I can't breath", "they cause panic attacks" and "you can't tell me what to do", aren't on the list.
Ironically I'm automatically coved, by an exemption. Yet it wouldn't occur to me not to wear a mask. They are for the protection of others, not me. And I have no right to put others at risk. It amuses me how many think they have that right.
So what you are telling me is that the exemption list drafted by PHE, and accepted by the government can then be ignored.
Now obviously I am sceptical to say the least about the validity of this information. To take it to it's logical conclusion (if your info is correct) it would mean that GP's can defy the government rules that are based on advice from PHE, despite the NHS being their employers, who are in turn funded by the government, and also via tax & ni payments from everyone in the UK. Some bizarre ideas our GP's seem to have then.
I am also a little confused by your post, as the start, and end of it seem to be contradictory,
start "Having just gone through this, I can say". as if you asked your doctor about exemption, end Ironically "I'm automatically coved, by an exemption. Yet it wouldn't occur to me not to wear a mask."
Why did you bother asking your GP, and effectively wasting his time when you would wear a mask anyway........................
However, as you seem to be well informed on all this maybe you can tell me if I would qualify with my current conditions.
Supplied on my monthly prescription with an inhaler because I have COPD.
Difficulty in handling some items carefully (such as a mask) due to Dupuytren’s Hand Contracture (a side effect of both liver disease & diabetes) in both hands.
Due to Diabetes I have the side effect of Peripheral Neuropathy to the point where if I had to put my walking stick down to put on, or remove a mask I would probably fall over sideways ???
