Tried litterally 20 time to get into my left tonight because that's what I'm up to, and just wouldn't go nerve, harder to insert. So I resorted back to the right leg for a second time in a row is this bad? Why was my leg doing this I havnt had this muc h trouble with it before. It took six times once but tonight was rediculas. What am I doing wrong. Mabey the cold muscle?
