Has Rebif been having the same problem with dull needles that the Copaxone has been having lately?

I hurt my right shoulder the other day, and couldnt use my right arm to do the shot on my right side, so I had my dad give me my shot of C last night...got a really dull needle. OMG! It felt like he was stabbing me with a dull steak knife! Almost as painful as using the autoject and a dull needle. Owwwwie!

The dull needles are what are making me consider switching over to something new.
