I called 111 over the weekend when I started to feel properly ill, then again at 4 this morning, when a very abrupt doctor told me they weren't testing so there was nothing he could do. Then spoke to my GP this morning who was so kind and understanding.
She referred me to a kind of triage centre we have in our town, where a nurse practitioner took my sats etc and listened to my chest.
She proclaimed everything was normal apart from my racing heart (which she put down to panic). She also listened to my chest and said it was totally clear, which should have been reassuring but hasn't been as much as I would hope, and told me when to take further action.
So it was really helpful to be seen by a real person, although the really paranoid part of me thinks she wouldn't have said if my chest sounded weird as they're trying to keep people out of hospital. I can't believe I've actually written that sentence - time to step away from Twitter!
