I know these too well! They're definitely debilitating and are worse when you're having a Lupus flare up. Unfortunately, my flare ups have been lasting longer and getting more painful.
I know how your feeling going through it now, I don't know why. Maybe the weather. Food. Or I say the older I get the worst I feel when I have my flare ups. To sores in my mouth, ears and nose. To my chest and joints hips worst. I just take warm baths. Try it if you can.
I use use a cold rags I find it to be great it take my dizziness go away
Yes, its a flare and yes that is exactly what mine feel like.
fatigue will be ongoing and probably the most problematic issue beyond painful days - you cannot rush to get up, that seems to trigger light headed feeling
