My experience was very positive, too. After maybe 10 days of a nasty bug, I was hit like like an express train with pneumonia (thank goodness one side only) followed almost immediately by pleurisy, which needed a chest drain for several days.
Very nearly 3 weeks in hospital, and a total of 5 weeks of ABs.
I couldn’t fault the care, from the ambulance crew, who arrived fairly quickly, to being blue-lighted straight into the emergency dept., to the subsequent care on wards.
As a normally robust and healthy person - I rarely need to see a GP - I will confess that it all came as something of a shock.
