I have no idea either but I would certainly like to know the answer to this too as my anethesist had to try 4 times until the epidural worked also, was quiet horrible and they were getting frustrated with me cause it wasnt working and they had no idea why, then talk began on putting me completely under and I said No way! I dont want to be completely asleep good thing 4th time was lucky. Im due to have another Cesar in 2 weeks so would be good to know if the spinal works differently fromt he epi.

Hope you find the answers charlismumma, good to see your opened to the fact that C section may be necessary, maybe it would be less traumatic for you if you were awake this time. Good luck!
