So I hit my head pretty hard as walking through a door way because I was very exhausted and not paying attention to where I was going and since then I’ve had bad head aches and pains behind my left eye also I’ve been shaky but I did have coffee today but it was like hours after I drank it looking at a screen that’s bright hurts my eyes and even when I was outside it hurt as well I do feel a little nausea as well and can’t move it get up too fast so I have a concussion or migraine?
