Hello again everyone, day 26ish here (except I reckon a week or two more than that without knowing it was COVID - but the last 26 days have easily been the worst illness I've had as an adult, and I've had some shockers!)
Shout out to anyone who has mentioned me in their posts, I really appreciate it but cannot for the life of me retain much detail or info in my noodle at the moment
so will only mention @stayathomegardener by name, and wanted to say how wonderful it was to read about Muriel being out yesterday and spending time with your DD in the garden! I have a lovely image of her wolfing lots of sarnies now that her appetite has improved, what a Trojan! And thank you for your email. More on that another time, but I was very happy to be included in the mail-out 
I took a double dose (500mg) of Cephalexin yesterday afternoon, to boost things a bit, and have taken 4 single doses since then. Due another before bed. I felt a huge improvement by this morning - much less pain and breathlessness and a feeling of wellbeing I thought I'd never have again. Unfortunately, the gains haven't lasted throughout the day. The horrid pleuritic pain has returned, although neither that nor the breathlessness are as troubling as they were until yesterday evening. So some progress, but I'm afraid I'll be like many of us and, while the antibiotics may make a dent, expect to be struggling with the virus itself for some time yet. After living with it for this long, I think we just know we know, right?! Still, baby steps towards healing and all that. I've still got at least another 5+ days on the antibiotic so we'll see.
I'm sorry to hear that some of you are also finding it so difficult in the 20days. Feel quite encouraged by the posts from people late 20s and early 30days who are having runs of feeling much better. It obviously improves in the weeks 5-6 stage for most. We'll get there. I agree with those discussing the differences in sensation between costochondritis and pleurisy - I've suffered costochondritis on and off for years and this is definitely different, and more depressing (for me at any rate). It was largely on the right rear- and side-ribcage until a few days ago, and jarringly restricted a lot of movement for me (hence why I worried I'd fragility fractured without realising). But in the last few days it has diffused into both sides of the ribs at the back and is a different sensation again, very unpleasant. Like having rocks in my lungs and across my mid back is how I'd describe it. Shudder 
Anyway, I treated myself this afternoon. Went into 'the good room' and watched Joker, which was superb. I hardly ever watch films these days, and rarely thrillers, but it was engrossing, for all its darkness. Nice to have a break from living in my bedroom too!
Sending
and socially distant hugs to all. Keep your eyes on that healing
