Annabel —
Have you tried using some kind of vibrator while you attempt dilation? The Candystick that Dr. Pacik recommends has helped relax my vagina and pelvic floor during dilation. During the first week to ten days of dilation (post-procedure), I also continued to use the Lidocaine lubricant mixture. This medicated-type mixture did / does provide a bit of a numbing effect that took away some of the pain/discomfort/ residual tightness. (what Dr. Pacik sometimes calls “strong virginal musculature).”
One other possibility to consider…. Prior to my visit / procedure with Dr. Pacik, my primary doctor suggested that I use Xanax to reduce anxiety during dilation. While I had my doubts about this (did not want any side effects, etc.), I will admit that I made far more progress with dilation using the Xanax than without it. Though I have not used the drug post the procedure, it may be something you wish to consider to assist you in these first few weeks.
I would include this question with your e-mails and logs to Dr. Pacik, and see what he might suggest moving forward.
Good luck!
