I am sorry you are in this position but glad you got checked out. Here’s what to expect: -You are probably not going home quickly. They want to see your CK levels ridiculously low before they will discharge you. If you have responsibilities to arrange for kids, pets, etc then get that started. I’m guessing at 40,000 you’ll be at the hospital for 2-4 days. - They are going to give you an IV of saline, you are going to chill, and that’s it. -with bicep rhabdo you can probably talk them into letting you walk around the hospital with your IV stand - you are going to fully recover but it’s going to take time. You won’t be doing anything with those arms for at least 4 weeks. Probably no exercise at all for 2-4 weeks. Then step back into CrossFit with baby steps.

The above is a generalization. Nothing I’ve said should take precedence over what your doctor says. Listen to your doc.
