hon, you will have a meeting with the anesthetic team in advance and let them know about the issues. They will need to use a smaller guage needle which will go through any spinal space. I have the same issues. I have calcification in my spine (which we only discovered as a result of trying to get the epi in) and I will have to have the smaller needle. When it is planned, they have more time to prepare and try different things so try not to worry too much. I've seen them get Epi's and Spinal's into patient I thought would never be able to take one!
