IMPORTANT signs along the way in General Board Posted June 15 I used to build websites for a living. It was too much screen time so I had to mostly retire. I wear high grade UV protected prescription sunglasses all day every day (see my avatar!). It seems to help with the light pain and discomfort. My neck and shoulders are always messed up even though I beat the beast with busting. The TMJ does not help the situation. I find certain sitting postures can be a trigger for me. Mostly a position like sitting up in bed watching tv or the couch can do it. Side sleeper here, on my back I get anxiety from the gravity pulling on my lungs and the belly is a no go for comfort.
