I got it today sliding in the floor. I sat on the floor and cringed at the pain for five min. Before I hobbled to the sink. I put cold water on it, and used an antiseptic cleanse and gel. After an hour or two it was still extremely painful!! Everyone keeps telling me I'm a baby and to stop complaining, but damn. It's awful. So I put some aloe Vera. With out alcohol remind you. And it burned like a mother Fer I jumped up and down in the stinging sensation. After that I took two otc painkillers, hoping it would help. Five hours later I can't even bend my knee without moaning. It can't be infected right? Any help?  I need relief! I have work tomorrow.
