IV catheter shear - How long will shear last in veins?

Recently, I was admitted to the hospital with chest pains. (about 45 days ago). I was put under observation overnight. The nurse tried to start an IV and couldn't. Then, she got another nurse...no dice. Then the charge nurse took a stab. FINALLY, they hit a vein in the fold of my arm. This was uncomfortable because I was told to keep my arm straight. I had a some kind of dye injected CT scan which I ume was to view my heart/lungs, etc. Well, about half way thru the night, it was driving me nuts having to keep one arm straight. So ....I asked the new nurse on duty to try again in a place where i could move my arms. She made an attempt.....Strike 1. At this point, 2 ICU nurses came into my room. One of these girls was pushing the needle in , pulling out, pushing in, pulling out, pretty much like a sewing machine. I never did see her hit blood (in the beginning part of the tube) but she ured me she hit a vein. I trustingly said, "mmmmkay" putting my faith in her abilities.....with reservation. This lady really hurt the hell out of me 'fishing' for a vein. Well these gals left and my nurse took the one out of the fold of my arm. Ahhh , the relief. I was able to sleep. As luck would have it, i didn't need any more IV therapy since the new cath was put in. Anyhoo, I was released the next morning. Both arms were black/blue/red from the top my arms to my hands. The morning nurse yanked and yanked the tape off my arm. The cath popped out. Well, the catheter looked a little shorter than the other ones the pulled out. I should know, they stuck me about 8 times. Is it possible they sheared off the cath? Should I have any worries? I don't want to look like an idiot going to get xrays for part of a tube stuck in me. If I did have a shaved off cath in me, circulating or stuck, would I most certainly notice it?
