I had my LP bent over the bed & the Dr. poked me 7 times & couldn't get it done right.
That sucker was giving up & said we'll just re-schedule it with the flouroscopy... I said no you won't I am going to lay down in the fetal postion & then you will have 3 more tries.... Well, finally he got it. Man I could have done some things to him right then if I could have stood up & lifted my left foot up then.
Just make sure youo stay hydrated like all of the others said.
