Hi Freedom - good to hear you’re getting up and seeing more ‘green’ / hope in the world. 
Talking about green(s)… 
I like the raw fruit & veg visible. My wife has given up putting it somewhere really cool, so that it lasts longer, because: When I see it, it entices me to eat it and I also see what needs eating first. In the small ‘front hall’ next to the kitchen we have a small table, where I have dishes or open plastic-containers with 1-2 chicory (endive), 4-5 carrots, 1-2 avocadoes, 1 zucchini, 1 cucumber, 1 celery/Chinese cabbage, 4-5 apples. Some of this for Harley & Stuey, who also love fennel & kohlrabi/Cabbage turnip, but they of course are just as veggie-fans as I am/have to be.
Since you like me have mainly fibro contributing to the pain and fatigue (despite in my case 30 diagnoses), and I also had this continual pain all over the place and often everywhere, perhaps I can think of things where to start to get some pains down. One big problem of course is doing something without making it or anything else (too much) worse…
The thing that now helps me most for these pains is my short twist-stretching the concerned limbs/parts. But I’m not sure if it’d been possible a year ago. But even worse then were the recommended long stretches & exercises which often made me nauseous & cramp. So might be worth trying. That (at least in my case) helps joint (which are my tendons), muscle, back, neck and rib pain, which you are mentioning and are also amongst my main pains.
Sometimes twist-stretching helps with burning, tingling, piercing & shooting pains too, sometimes I can pressure it away (like stabbing pains in fingers & toes) and sometimes I just have to wait and detach or distract myself mentally…
The other thing for me, for all these types, is arnica complex cream (‘Traumeel’, a bit homeopathic, a bit herbal, not sure how far you’re into that), but not rubbing too long or hard, otherwise my elbows and wrists hurt more, or I have to rub them too.
Not sure about trying heat or cold, perhaps just quick under the tap, not too long?
Others’d suggest nerve supps like Magnesium & B-Vitamins, but they’re expensive, unproven and for me they were unhelpful.
Is gentle osteopathy or chiropractic or similar an option?
Walking btw is still an issue for me too, despite all my progress. Apart from cycling instead, which won’t be an option for you, or keeping it short, I put my legs up against a wall before and after (and sometimes in between on a bench, to be honest)…
Anything here that helps?
