Good Morning, We are new to this forum. Still navigating our way through my son's illness. In the spring he had been very sick with a sore throat, fever, etc. Then he developed tics and weird movements, age regression, etc. We are fighting doctors for tests, etc. His MRI did come back clear. My son recently started having muscle twitches, especially in his face. Has anyone else's children experienced this? He is taking magnesium. Please share your experiences. So thankful to have this forum!
