My daughter recently had three distinct episodes where she lost control of her muscles. Twice it was almost dropping a cup and once almost fell down. She knows it happens, but just after it happens. It's never been more than a second or so. There are no other noticeable symptoms. No fever, no headache, etc. she does have an allergic reaction to bug bites, and we see a few of those, but typically it is just swelling around the bite.
