I've come to the conclusion winter is bad for me.
Everything bad has started in winter, including Crohn's (although I received the actual diagnosis in summer, it had started about
6 months earlier). The majority of my severe flare-ups have also happened in autumn or winter. The winter before last I had continous cold sores for 3 months. Last winter I had fun with uveitis, only that - unlike the cold sores - didn't go away. Oops, nearly forgot the shingles I got last winter too.
I'm just waiting to see what befalls me this this January
