Hey everybody, After reading about the conditioned response in the expert forum it got my wondering how the mind creates symptoms in various situations and how it can create symptoms you pay the most attention to. For example, lately I have noticed more double vision with my eyes, I have been paying more attention/worry to it, and I Made this cause and effect relationship between my eye pain and the double vision. Its another one of those inconsistencies that doesn't make sense. I have barely been on the computer over the past 4 days (I worked one 8 hour day on the computer on Monday) and I still have the symptoms full strength and was noticing the double vision more yesterday even though I was outside looking into the distance. It seems the more concern I have over a particular symptom the more I seem to have it. Does this make sense from a psychological point of view? This also happened in the past where the more I read about the condition, the more I learned to be worried about like going out in the wind, watching tv, reading a book, just looking out in the distance, and each one of these examples I was told not to do that so I think it planted a seed in my mind. I think these are all conditioned responses from learning about something, worrying about it, and then if I do that activity I have the fear in the back of my mind that it will make the eye strain worse so it does. One other interesting thing is the pulling sensation i feel in my eyes. I started worrying about the pulling sensation about 2 years ago and now that is the primary symptom I have. I kept concentrating on that one symptom and getting rid of it during vision therapy.
