vitamin d should reduce inflammatory problems and the majority of people are deficient in it, especially people with darker skins living in northern countries (vitamin d absorption may well be the major factor in differences in skin colour). also vitamin d isn't the type where it can be usd as soon as you take it; it needs some time before it gets into usable state, and we have a supply to use from that needs regular topping up.
the rda for vitamin d is FAR too low - it'll stop ricketts, but that's all, you want to be taking somewhere between 50 and 100 micrograms a day rather than the absurd recommended 8-10. when the c19 thing started and people were going on ventilators due to suffering a cytokine storm, that was down to a vitamin d deviciency. in winter you need to particularly take vitamin d due to the lack of sunlight. if you read about t cells and the body's secondary defences (after antibodies), it runs on vitamin d, and a shortage of vitamin d tips it down the inflammatory route (perhaps leading to cytokine problems). it's vitamin d3 we need, not d2 (d2 is plant based and chocolate teapot territory).
for muscle problems it might also be worth talking to a physio. if you spend ages at a computer, make sure you sit square in front of the keyboard and screen and don't sit twisted for any amount of time.
