Yes, all the time. With conversations, events, streets, names, spelling of words, grammar, location of items, messages I posted and read and etc. Maddening isn't. I never had this problem. In fact, I felt I had like a photographic memory.
In the beginning I really struggled with this loss to the point of being upset. But today, I shrug it off, blame Lupus and say it will come to me when it does. It helps keep the stress at bay and too, I find when I don't fret over it, the recalling comes faster.
I asked my rheumatologist about this and he said it wasn't Lupus related. I have SLE and Sjogrens Syndrome. He never gave another possibility and well, I forgot to ask.
From my reads, there is such a think as Lupus Fog...the inability to concentrate. And from others' experiences, forgetting is a symptom of Lupus. I do know it is real regardless of what my doctor said.
Sometimes I wonder like you, is it the medicine that contributes to it too? Especially the prescriptions for pain and anxiety. I believe anti-depressants can do that also. I dose with Plaquenil, Ultracet (Tramadol), Requib, Xanax and spray my mouth with Aquoral.
What was the craziest, I could not remember my rheumatologist's name, what is office looked like, where it was. I had been there twice before. I panicked. I looked in the yellow pages for a familiar name. They all seemed foreign. Did an Internet search. Nothing. Waited a few days, still couldn't recall then it dawn on me, his name is on my prescription bottle. What a relief for me.
That was the event I told my doctor of when he said it wasn't Lupus related.
My aide to help with my memory is write it down, unfortunately I didn't write my doctors appointment that time. Use Post'ems. Lots of them. Buy by the bulk.
