Struggling with Illness and EDS Pain

I would go to urgent care or even a walk in clinic and do a flu and covid test. Definitely sounds like a bad infection but some of the symptoms don’t line up with a cold or even flu - of course everyone’s symptoms vary. Best to catch it earlier; if you’re still in first days of symptoms you can likely start an antiviral treatment

I don't have EDS so take my opinion with a grain of salt. But the skin sensitivity in particular sounds like how it felt when I had COVID. I was weirdly sensitive to so many things. Like I normally have sensory issues but it felt like electricity in my skin. Or like everything had tiny needles on it. And the same other symptoms that you described too. I also had weird cramps in my arms that somehow gave me long lasting damage to my right shoulder. Its been a year and it seems to be finally healing but it was randomly in pain a lot through the last year. It just kinda felt achy at first but got worse as I got sicker. Again, could be something to do with EDS. Or it's the flu. But it just sounds eerily similar to when I had covid
