I swim sometimes for excercise. But lately I've been getting 'swimmer's headache.' It is the worst feeling. It is caused by goggles being too tight. It is when you get out of the pool and you feel like you took a vicodin, have a migraine, and someone is cutting off oxygen to your head while squeezing it, all at the same time. And you usually feel this after you get out, and take off your goggles, not while swimming. It makes it hard to drive home. Anyway i recently got a pair of TYR performance goggles and loosened them all the way and they're too tight. And it's not like have an abnormally large head or anything. I'm of average height. I was wondering if anyone could suggest some comfortable goggles that i could try. Or that do not make you want to kill yourself when you're done usin them. PS: on a mac related swimming note check these out.
