Marni that's wonderful!

Don't stress about your cardio. Some people can take weeks to completely flush anesthesia from their system...I wasn't able to test things after my back, but it took me 6-8 weeks to recover and get back into running shape after a very minor procedure about 3 years ago. Your body is just stressed and you'll improve exponentially as things start to heal and get back to normal.

You got this!
