I guess a good thing to do initially, would check with a doctor first to see if this is a mundane physical problem (even a potentially serious one) instead of assuming it's energy related. In other ways, it could be psychosomatic. I know the feeling of that, because before i've also kind of created and reinforced a little problem and made it a big problem. It was something similar. A kind of dull tension in my eyes and head that made silent sitting pretty difficult. Only, because i made it a problem by focusing on it. I also stopped chakra work for months, and that in itself took away the focus on the problem.
