I have had this what I call "a body stutter" and it usually happens when I'm really tired and get up quickly or highly stressed. I am taking medication, it still happens. I have talked with my neurologist and I don't think I'm describing it right to him. I can feel something is wrong before it happens like I'm not able to focus and I also have a tingling feeling in my upper back and head. When that comes on I know I have to grip on to something so I don't fall. I'm not sure what kind of seizure I might be having, because it only happens in seconds and it may happen several times in the morning till my medication kicks in. I get very frustrated because I have no control as I'm sure do others with seizure issues. If someone could help me figure this out.
