Lately my head has been jerking in its own, mostly when im feeling something (annoyed, mad, etc) or it happens at random. Barely, but sometimes my eye twitches and/or i squint or scrunch up my face. Sometimes thers violent jerks, like one time i jerked my head and i blacked out for a second, then my neck started clicking afterwards. Do you know why this is happening? Do I have something? This has really been disturbing my school work since I’m used to writing sloppy and everytime I write something over the line like when I’m taking notes my neck starts jerking. Please help.
