Brain fog

I have had brain fog and I’ve wondered if it is because of my RA? Anyone else have brain fog? It comes and goes. I’m on Arava now and I felt like it was helpful with the brain fog ( super helpful for my body) but it returned yesterday… probably because with this sub zero weather, I’m having a flare up. Is this something I should leave a message for my doc about ? 🫤 I own a seasonal business and I dread having to face the public on days I have a wall that just won’t allow me to remember a customer’s name 😖 last season I had to turn away a couple customers because I was off medication during season ( because of an allergic reaction to my RA med) I was struggling to pick up things and some days walking was a struggle. I just don’t wanna have 2 seasons that I fail even one customer 😕
