I got hit with a ball in the back of my head at the end of February this year. Diagnosed with concussion. I was told by neurosurgeon that symptoms could last 2 years or more. I’m still having unbearable headaches in the back of my head, down my neck and into my ears. My ears are ringing so loud now also. I seem to have all The symptoms list on this website. Has anyone found and treatments/drugs etc. that help alleviate these symptoms?
