Hi, I have developed this sort of habit, where I raise my forehead from time to time. Sometimes , I even raise my head up to the sky. I do it quite often and more so during stressful times. I developed this habit 4 years ago when I was going through a very stressful period. It may be a nervous tic or a muscle twitch, I don t know. It gets really annoying sometimes and i feel my head is constantly under some strain. My forehead and the back of my neck feel some strain.
