I've been injured the unconventional way. No arm , wrist, shoulder, elbow injury. I was injured in my eye. yes..that's right the eye. When i change my strings i usually don't cut the excess string off for like a week. So i was playing one day and had the point off the string go directly in my eye, talk about pain.. my god i thought i was gonna die. My eye was messed up and irritated for like 2 weeks.
