I was initially thinking it sounds like this, but it only lasted for just over 24 hours. Came on weak at first, then climaxed at one point in the day, and then started tapering off in pain level, until it was almost imperceptable when the pains would come in. I didn't have any impact to my vision, although my eye felt "off", hard to explain, for a day. But mostly normal now (back to my normal double vision anyway...)
