Half jokingly, patients with chronic pain can sometimes start to wonder whether they are coming down with Alzheimer’s. They don’t seem to remember anything anymore. Besides memory problems, it can be hard to concentrate, multi-task, and find the right word to use – that experience when the word you want to use is “on the tip of your tongue.” People with fibromyalgia have even given these problems a nickname – “fibro fog” – as in when your head is in the clouds.
