Thanks so much Abbie!! I looked up "lumbar sympathetic block nausea vomiting" on different search engines and couldn't find anything... I thought it was just me from the LSB or that I must've been vomiting from the pain again. Confusing!

Thanks again for letting me know. Did you find that the blocks were worth the nausea/ vomiting? I am not sure if I want to continue to do blocks if they only last a few hours (the dr is 3 hours away, the block lasted 2 hours... so I wasn't even home yet and it wore off!), and I am so far away from the dr and am going to have this each time... ?!
