Hi. This is my first post. Suffered serious concussion when I feel as I was having stroke 11 months ago. Worst symptoms that remain are extremely painful headaches and extreme exhaustion. Headaches are sometimes accompanied by dizziness and nausea and vomiting. Have tried multiple modalities. While it use to be constant and is now less than constant, it is frequent. Anybody going through same type of symptoms. Have you found relief? What's worked for you? Many thanks in advance.
