I find those intermittent symptoms often the hardest to deal with. I have an issue with hemiplegia, one side of my body seems to give up. I can go weeks and all seems OK, then I can have a day or even just a few hours when my arm or my leg or my whole right side goes all tingly and won’t work properly. I can never tell when or why or how bad it’s gonna be. It can start off as a pins’n’needles in my hand and only affect my hand or it can progress to include my eye, my arm and my leg not to mention the headache.
If it was a daily thing, OK, I’d just add it to my list and know that it was going to happen, but when its so varied I can’t tell, I can’t plan around it. A bit like you, when I think all has settled and things were looking up… …here we go again. I’ve tried to explain it to others but just get a look of disbelief, but it is nice to know I’m not the only one dealing with intermittent symptoms, even if it does annoy the daylights outta me.
