Well, it's done. Far less discomfort than I expected, still feel tired and a bit ziggly (see earlier post!), but far better than I expected. For anyone about to have a cryoablation, let me reassure you, the expectation is FAR worse than the experience!! It was fascinating to see bits of me on the screen that I hadn't seen before, my cardiologist \ EP was tremendously informative and reassuring, explaining what I could see, and what he was about to do before he did it. Minimal pain (discomfort really) then back to the ward for recovery 4 hours later. Stay in overnight, then ECG and home. Lets see how the recovery goes.
Don't be afraid, you really are in the best of hands, treat it as an experience you can learn from, and hope we all can recover in our own way and time. Thanks for all the support from everyone on here, it's lovely to know that what you are feeling is not unique, and that you will get through this.
