Hi Sams!
I am actually setting up my appointment for my CESI this week. I know with my Occipital Nerve Block, unfortunately, at least for me, it took 7 weeks for the pain to go away and needless to say I wasn't sure which was worse, my daily migraine or the pain from the block but things do happen. However, I am looking forward to seeing if the CESI can work. I get 20 or so migraines a month, so I am keeping my fingers crossed.
Good luck, and I will keep my eyes open and will be hoping you wouldn't mind sharing how the procedure is working for you! I am hoping that you are pain free at this time too!
