Seems very strange that you did not have a prep, the surgeon needs to make sure that you are compatible for the procedure. It does sound as though you may need to go to another clinic, you explain what has happened, make sure you ask as many questions as possible, and you are satisfied with the answers. Definitely agree with efflux if you are experiencing any doubt you should walk away. Try not to worry, this issue can be resolved, unfortunately it appears it's just been down to an untrustworthy surgeon that has mislead you.
