Hi, I'm so sorry about your assault. I was hit by a car while riding my bike six month ago and am still suffering from headaches every day. Sounds very much like you have post-concussion syndrome. Besides the headaches, I still feel somewhat dizzy or more spacy - really hard to describe. I also had the extreme head pressure and tension. Like others on this forum I have not really found anything that helps much. I take Fioricet for headaches, but it should not be taken long-term. Please remember that the head pain is not life-threatening, but I know it is debilitating. My life has been on hold since mid-May.
