Constant lightheadedness/ head pressure
Hello, I'm a 16 year old girl. Almost a month ago I had felt a strange bursting feeling on the left side of my head. Ever since then, I've felt lightheaded, dizzy or unusual head pressure. 4 days later I went to the ER and they did a CAT scan & lumbar puncture and found nothing major was wrong. They told me that they were just going to call it a headache. In my follow up appointment with my family doctor, he suggested it was sinuses. He gave me sinus infection pills and sent me home. My sinus infection has gone away and my head still feels wrong. It feels as though it were floating in the clouds. It doesnt get better or worse when I do anything in particular (I.e doesn't get worse when I eat) I tried migraine medicine and it seems pretty ineffective. I've lost most of my appetite. I don't know what to do. Any suggestions?
