Ok, I'm confused, but going to reply anyway. First - I would never be working out at a gym where needles could be found laying on the floor. I dont care if it's in the bathroom or the gym floor, if I saw one on the floor even once I wouldnt go back. Second, if any of my needles hit the floor even at my home, I would toss it and get another and I consdier my house spotless, but even if it hit the floor, it's headed for the trash. Third, GO TO THE DOCTOR!!!! now... HIV and or AIDS will not show up right away, but they could start on Monthly montoring process on you and try for preventative measures. Besides i understand why that would be running through your head, but you have other things to worry about, such as infection, etc.
I hope that youare messing w/ us, but GOD be w/ you if your not.
And one last statement, like stated above by burnthiscorpse, if you cant inject yourself you shouldnt be using gear,..... I would like to add, if you cant use your gear in your own home, you shouldnt be using gear!!!
