It all started 5 months ago. I can't think clearly, feel disconnected, difficulty in remembering things and pain in neck which occur when i move my head sideways and upward and is permanent and also involuntary muscle movement which occur sometimes.It all started from the day when i studied 6hrs non stop focusing on my book with my neck downwards. At that time i had head spinning but it went down of its own in 2 days but left these symptoms to me. Currently i am in consult with a doctor but he is not able to help much. I sleep 8-9 hrs regularly. I always live happy and I don't think its a case of depression. I think due to neck problem i am having these symptoms. Please help Thank You
