spent half an hour in direct sun at my niece’s graduation last weekend. no sunscreen, wasn’t thinking (stupid move). by evening my hands were puffy. by monday my joints were locked worse than they’ve been since starting the biologic eight weeks ago. went back through my tracking. every significant flare has sun in the backstory. not just the photosensitivity rash - actual joint inflammation. idk, hands swelling at 3am. labs wednesday: anti-dsDNA climbed, C3 dropped. like someone reset three weeks of improvement. my rheum said photosensitivity triggers get massively underestimated. people focus on the uv rash, miss the systemic flare underneath. she’s right. i can cover the rash. the stiffness that shuts down my patient consults? that’s the real cost. the pattern only became obvious once i had enough data logged. flares plus dates plus what preceded each one. one afternoon in sun, now i’m paying through friday. does anyone else see sun as a hard trigger? does tracking actually help you predict when it’s going to set you back?
