Hi, I felt moving sensation in my head two years ago. Later i consulted doctor and was asked to go for Scan. Doctor believed it was due to tension gave me a medicine. For months i was okay. But again i started feeling the same with more movements than earlier. This time i feel the sensation in larger part of brain in comparison to past. Previously i used to feel moving sensation only at the time of sleeping, but this time i feel all the time. Kindly suggest me what should i do?
