I had a peth shot prior to both c-sections as I presented in labour 2 days before the c-section date, I didn't feel a thing. I would recommend having a thorough conversation with your ob and the anaesthatist this time around. Also is there anyway of obtaining the medication list/details from Eithan's birth so that next time around they know what not to do, and how to make it a much better experience for you.
Best of luck
