Ohh good for you! A picc line is easy peasy and a Saranwraper will be perfect! You won’t rip out the line! It has a seal placed around it and it’s in until your nurse removes it when no longer needed. So don’t worry about that.
You may not need anything else. Over my months of treatment for AML, I did have 3 different picc lines. One of them was annoying in that the lumens on the picc line would get snagged up in my clothing. *different arm… (lumens are the hook up lines for IVs that dangle off the picc line)
So I had some fun, whimsical knee socks that I cut off at the ankle and used those for the ‘sleeve’ around my arm. ☺️ They had cute designs and my nurses were wondering where I got my cool sleeves. (Sshhhhh. 😆)

LOL. Yes, Amazon can find you anywhere! Even at my hotel for 4 months! 😂.
The bio body electrolyte should be a good means of hydration for you. One thing to note, is that you should run this past your transplant pharmacist first. Just to make sure nothing interferes with your meds.

You’re ready gurlfriend! You’ve got this!! 🧬We’re GO for transplant!
