I have no big deal about 9cm needles, but I didn't want an epidural in the first place!

Actually, I'm thinking "only 9cm?" because everyone goes on about how big they are! 9cm doesn't seem that big when you think it has to go in your spine and leave bits sticking out, I assume that if a blood presssure cuff won't fit on your arm due to obesity that a 9cm needle won't reach your spine.
