Sannah,
Hi there... Well your body wants to get 100% healthy doesn't it it's taking care of everything right now so you can recover and be healthy and happy from here forward.
Now about those stones.... Grrrrrr.... Painful lil buggers.... Get them zapped/broke apart into tiny fragments while you are in the hospital... Then once they are broke up tiny into particles your iv lines will push thru lots of good fluids to push them out! Ask them to do this while you are there... Before your gallbladder removal or under the same anesthesia they can shock wave them and get that gallbladder as well.
Oh it would be so good if this could be arranged as I know you want to minimize your hospital stays.
Request a consult with a urologist/nephrologist and general surgeon. I bet they can master up a good plan for you. All the iv fluids are really going to help your kidneys.
I'm keeping you in my prayers!
After this you are going to be fabulous! Just you wait and see xoxo!!
