My seven year old had his legs suddenly go out & dropped to the floor. He sat for a couple seconds then got up and ran off. He looked really sleepy after that. Past history deletion in chromosome 17p13.1, ESES, partial complex seizures, intellectual disability, ADHD, sensory processing disorder. A week ago he had three baby teeth pulled- no problems or complaints. Green sinus drainage since Saturday. Just concerned that his seizure disorder is evolving-again. Any thoughts on this?
