Something right below my right eye Iin the eye bag area) has been twitching for several hours, and I don t know whether or not to be concerned. I don t seem to have any other symptoms - no headache, etc. - and as far as I can tell my vision is not affected. If I hadn t noticed it in the mirror this morning, I wouldn t be aware that it was happening; in other words, I can t feel anything. If it doesn t stop on its own soon, should I see a doctor? Could it be a sign of something serious?
